Subject: Make sure that tp_free frees the int the same way as tp_dealloc
 would. This fixes the problem that Barry reported on python-dev:    >>> 23000
 .__class__ = bool crashes in the deallocator.  This was because int inherited
 tp_free from object, which uses the default allocator.

2.2. Bugfix candidate.
