These days we have PyGILStateEnsure(): http://docs.python.org/dev/c-api/init.html#PyGILStateEnsure

and even dedicated documentation: http://docs.python.org/dev/c-api/init.html#non-python-created-threads ;) That is awesome!

Although, if it's possible to arrange it, it's still better to do that once and then use BEGIN/END_ALLOW_THREADS to avoid the overhead of creating and destroying the temporary thread states: http://blog.ccpgames.com/kristjan/2011/06/23/temporary-thread-state-overhead/

Still, it's far, far easier than it used to be to handle the GIL correctly from non-Python created threads.

Cheers, Nick.
