Wouldn't it be better to expose and re-use the HEAD_LOCK and HEAD_UNLOCK
macros from pystate.c?
That said, I doubt this is the issue here. We are removing a string key pointing
to a localdummy object. Both are small atomic types not handled by the GC, so
I don't see how deallocating these objects could release the GIL.
