Fix inconsistency in range function argument processing: any non-float
non-integer argument is now converted to an integer (if possible) using its
__int__ method.  Previously, only small arguments were treated this way;
larger arguments (those whose __int__ was outside the range of a C long)
would produce a TypeError.

``sys.argv[0]`` is now set to '-m' instead of '-c' when searching for the

Remove the 16KB stack-based buffer in ``PyMarshal_ReadLastObjectFromFile``,

allocation fallback.  Patch by Charles-François Natali.

doesn't give any detailed explanation.

asyncore.dispatcher's __getattr__ method produced confusing error messages
when accessing undefined class attributes because of the cheap inheritance
with the underlying socket object.  The cheap inheritance has been
deprecated.

Fix precedence of signals in Decimal module: when a Decimal operation raises
multiple signals and more than one of those signals is trapped, the
specification determines the order in which the signals should be handled.
In many cases this order wasn't being followed, leading to the wrong Python
exception being raised.

The close() method of :mod:`io` objects should not swallow exceptions raised

Fix a race condition in SocketServer.BaseServer.shutdown, where the method

Fix the unwrap() method of SSL objects when the socket has a non-infinite
timeout.  Also make that method friendlier with applications wanting to
continue using the socket in clear-text mode, by disabling OpenSSL's
internal readahead.  Thanks to Darryl Miles for guidance.

Turn off optimization in ``--with-pydebug`` builds with gcc. (Optimization
was unintentionally turned on in gcc --with-pydebug builds in 2.7 beta1 as a
result of the issue #1628484 fix, combined with autoconf's strange choice of
default CFLAGS produced by AC_PROG_CC for gcc.)
