-Why am I going on with so much detail about this?  Because when threads are

-thread state data structure for them.  Such threads must bootstrap themselves
-into existence, by first creating a thread state data structure, then acquiring

 Threads can take advantage of the :cfunc:`PyGILState_\*` functions to do all of
 the above automatically.  The typical idiom for calling into Python from a C
