-"PYSTONE" Benchmark Program
-
-Version:        Python/1.1 (corresponds to C/1.1 plus 2 Pystone fixes)
-
-Author:         Reinhold P. Weicker,  CACM Vol 27, No 10, 10/84 pg. 1013.
-
-                Translated from ADA to C by Rick Richardson.
-                Every method to preserve ADA-likeness has been used,
-                at the expense of C-ness.
-
-                Translated from C to Python by Guido van Rossum.
-
-Version History:
-
-                Version 1.1 corrects two bugs in version 1.0:
-
-                First, it leaked memory: in Proc1(), NextRecord ends
-                up having a pointer to itself.  I have corrected this
-                by zapping NextRecord.PtrComp at the end of Proc1().
-
-                Second, Proc3() used the operator != to compare a
-                record to None.  This is rather inefficient and not
-                true to the intention of the original benchmark (where
-                a pointer comparison to None is intended; the !=
-                operator attempts to find a method __cmp__ to do value
-                comparison of the record).  Version 1.1 runs 5-10
-                percent faster than version 1.0, so benchmark figures
-                of different versions can't be compared directly.

-def find_unused_port(family=socket.AF_INET, socktype=socket.SOCK_STREAM):
-    """Returns an unused port that should be suitable for binding.  This is
-    achieved by creating a temporary socket with the same family and type as
-    the 'sock' parameter (default is AF_INET, SOCK_STREAM), and binding it to
-    the specified host address (defaults to 0.0.0.0) with the port set to 0,
-    eliciting an unused ephemeral port from the OS.  The temporary socket is
-    then closed and deleted, and the ephemeral port is returned.
-
-    Either this method or bind_port() should be used for any tests where a
-    server socket needs to be bound to a particular port for the duration of
-    the test.  Which one to use depends on whether the calling code is creating
-    a python socket, or if an unused port needs to be provided in a constructor
-    or passed to an external program (i.e. the -accept argument to openssl's
-    s_server mode).  Always prefer bind_port() over find_unused_port() where
-    possible.  Hard coded ports should *NEVER* be used.  As soon as a server
-    socket is bound to a hard coded port, the ability to run multiple instances
-    of the test simultaneously on the same host is compromised, which makes the
-    test a ticking time bomb in a buildbot environment. On Unix buildbots, this
-    may simply manifest as a failed test, which can be recovered from without
-    intervention in most cases, but on Windows, the entire python process can
-    completely and utterly wedge, requiring someone to log in to the buildbot
-    and manually kill the affected process.
-
-    (This is easy to reproduce on Windows, unfortunately, and can be traced to
-    the SO_REUSEADDR socket option having different semantics on Windows versus
-    Unix/Linux.  On Unix, you can't have two AF_INET SOCK_STREAM sockets bind,
-    listen and then accept connections on identical host/ports.  An EADDRINUSE
-    socket.error will be raised at some point (depending on the platform and
-    the order bind and listen were called on each socket).
-
-    However, on Windows, if SO_REUSEADDR is set on the sockets, no EADDRINUSE
-    will ever be raised when attempting to bind two identical host/ports. When
-    accept() is called on each socket, the second caller's process will steal
-    the port from the first caller, leaving them both in an awkwardly wedged
-    state where they'll no longer respond to any signals or graceful kills, and
-    must be forcibly killed via OpenProcess()/TerminateProcess().
-
-    The solution on Windows is to use the SO_EXCLUSIVEADDRUSE socket option
-    instead of SO_REUSEADDR, which effectively affords the same semantics as
-    SO_REUSEADDR on Unix.  Given the propensity of Unix developers in the Open
-    Source world compared to Windows ones, this is a common mistake.  A quick
-    look over OpenSSL's 0.9.8g source shows that they use SO_REUSEADDR when
-    openssl.exe is called with the 's_server' option, for example. See
-    http://bugs.python.org/issue2550 for more info.  The following site also
-    has a very thorough description about the implications of both REUSEADDR
-    and EXCLUSIVEADDRUSE on Windows:
-    http://msdn2.microsoft.com/en-us/library/ms740621(VS.85).aspx)
-
-    XXX: although this approach is a vast improvement on previous attempts to
-    elicit unused ports, it rests heavily on the assumption that the ephemeral
-    port returned to us by the OS won't immediately be dished back out to some
-    other process when we close and delete our temporary socket but before our
-    calling code has a chance to bind the returned port.  We can deal with this
-    issue if/when we come across it.
