Issue 3723: Fixed initialization of subinterpreters The patch fixes several issues with Py_NewInterpreter as well as the demo for multiple subinterpreters. Most of the patch was written by MvL with help from Benjamin, Amaury and me. Graham Dumpleton has verified that this patch fixes an issue with mod_wsgi.
