It used to work perfectly in 2.2. Thus my dilemma.

But, I'm not looking for a replacement for per-thread state. I am actually
maintaining multiple *interpreters*, each with all those global variables
you talked about. I need to do this because I want to be able to create an
"environment", load some scripts, run them, then delete that "environment"
without affecting other "environments".
If this PyGILState actually is an entire Python interpreter environment,
then I'll happily switch to it.
