/* An extension mechanism to store arbitrary additional per-thread state.

Browse source 
PyThreadState_GetDict() returns a dictionary that can be used to hold such
   state; the caller should pick a unique key and store its state there.  If
   PyThreadState_GetDict() returns NULL, an exception has been raised (most
   likely MemoryError) and the caller should pass on the exception. */
