I mentioned it before but I have this patch for boost python that adds code to lock and unlock the gil at all the boundaries I have found between python and boost python. This makes it so multiple threads can call into python without the user having to lock and unlock the gil themselves. I am pretty sure this is a very much desired feature but I guess the developers are waiting for a head start, so here is the patch file that can be applied to the boost trunk or any of the 1.4x versions of boost python. I would very much like to see the patch correctly worked into boost python so I no longer have to maintain it myself. I have been using this in my application for a few months now and I am fairly confident in its completeness when NOT embedding python interpreters. There may be more entry points I have missed because I do not embed python in my app, therefore I would say this patch is only non-embedded systems.
