Someone can correct me if I'm wrong, but the lock actually lives in
ceval.c, around here:
802 PyThread_release_lock(interpreter_lock);
803
804 /* Other threads may run now */
805
806 PyThread_acquire_lock(interpreter_lock, 1);
This was taken from what appears to be a 2.4.1 release rather than a CVS
checkout. It looks like the PyThread_type_lock is defined in the
thread_xxx.h files, though.
