Don't pass a NULL traceback to PyException_SetTraceback(): pass Py_None.
Passing NULL would raise a new exception.

exception was not raised.

Before the process was killed by SIGALRM in another random test (1 second later)

on memory allocation failure

and _PyUnicode_HAS_WSTR_MEMORY() macros

These macros are called in unicode_dealloc(), whereas the unicode object can be
"inconsistent" if the creation of the object failed.

For example, when unicode_subtype_new() fails on a memory allocation,
_PyUnicode_CheckConsistency() fails with an assertion error because data is
NULL.

if the function called failed whereas no exception was raised, to detect bugs
earlier.

Check if XML_ParserCreate_MM() failed (ex: MemoryError) before using
self->itself.

The "Gestalt" function on OSX is deprecated (starting with OSX 10.8),
remove its usage from the stdlib. The patch removes a number of private
functions and a private module, but does not change the public API.

The removed code was effectively dead, the platform module has used
other code to fetch the OSX version for years and could only use
on the Gestalt-based code as a fallback. That fallback can only trigger
on broken OSX installs (that is, someone has removed parts of the system
install)
