the range of ints.  The old code would pass random truncated bits to
sq_repeat() on a 64-bit machine.

for their contributions to the snake farm.

Because ob_size is a 32-bit int but sys.maxint is LONG_MAX which is a
64-bit value, there's no way to make this test succeed on a 64-bit
platform.  So just skip it when sys.maxint isn't 0x7fffffff.

iter(self.keys()).

Note that distutils.core.DEBUG still works if client code uses it, but
the core code avoids circular references by using distutils.debug.

but returns r->len which is a long.  This doesn't even cause a warning
on 32-bit platforms, but can return bogus values on 64-bit platforms
(and should cause a compiler warning).  Fix this by inserting a range
check when LONG_MAX != INT_MAX, and adding an explicit cast to (int)
when the test passes.  When r->len is out of range, PySequence_Size()
and hence len() will report an error (but an iterator will still
work).

This makes things a touch more like 2.2.  Read the comments in
Python/ceval.c for more details.

more instances of the bizarre "del f; del m" ways to spell .close() (del

with a size larger than the underlying file worked on Windows.  It
does <wink>.  However, merely creating an mmap that way has the side
effect of growing the file on disk to match the specified size.  A
*later* test assumed that the file on disk was still exactly as it was
before the new "size too big" test was added, but that's no longer true.
So added a hack at the end of the "size too big" test to truncate the
disk file back to its original size on Windows.

boundary could be found -- in a lax parser -- the entire body is
assigned to the message payload.

_handle_text(): Use _isstring() for stringiness test.

_handle_multipart(): Add a test before the ListType test, checking for
stringiness of the payload.  String payloads for multitypes means a
message with broken MIME chrome was parsed by a lax parser.  Instead
of raising a BoundaryError in those cases, the entire body is assigned
to the message payload (but since the content type is still
multipart/*, the Generator needs to be updated too).
