+- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
+ format code incorrectly truncated the length to an int, even when
+ PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
+ results with huge strings.

- Issue #1402: Fix a crash on exit, when another thread is still running, and
if the deallocation of its frames somehow calls the PyGILState_Ensure() /
PyGILState_Release() functions.
