Having a context manager to say "don't release the GIL" for a bit could actually be really nice (e.g. for implementing builtin-style method semantics for data types written in Python). However, two immediate questions come to mind: 1. How does the patch interact with C code that explicitly releases the GIL? (e.g. IO commands inside a "with atomic:" block) 2. Whether or not Jython and IronPython could implement something like that, since they're free threaded with fine-grained locks. If they can't then I don't see how we could justify making it part of the standard library. Interesting idea, though :) Cheers, Nick. -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
