OK: further.

Two options are suggested:

There are different options to solve this issue:

* Reset _tstate_lock before using it... not sure that it's worth it, since we are going to delete the threading.Thread object with its _tstate_lock object anymore. After calling fork, the child process has exactly 1 thread: all other threads have been removed.

* Modify release_sentinel() to not use the lock: avoid PyThread_release_lock() call.

** as to option 1 - it is 'worth it' if it stops the crashes

** This is deeper than I usually go in Python code - but I'll make an effort - help is appreciated.
