Merge rev 42607 from the trunk.
 
Patch 1413181, by Gabriel Becedillas.

PyThreadState_Delete():  if the auto-GIL-state machinery knows about
the thread state, forget it (since the thread state is being deleted,
continuing to remember it can't help, but can hurt if another thread
happens to get created with the same thread id).
