I agree.  What is the best way to do that?  PL_curinterp == NULL?
PL_thr_key == NULL?   It looks to me that dTHX translates to
pthread_getspecific(), which returns an undefined value before the
key is initialized, so we can't depend on dTHX to tell us whether we
actually have a thread context or not.

The case I am most worried about, though, is the one where we
allocate before thread context is initialized and deallocate after
(possibly during global destruction).   Is global destruction
supposed to be smart enough to recognize things that were created
before there was a thread context and deallocate them differently?
