I'm embedding python15.dll in a Windows application, and will be running z2.py one of the many thread/interpreter pairs. At some point my .exe has to be closed, I need to get Zope to shutdown as if I'd pressed the shutdown button in the control panel. Is there any way I can acquire the intepreter lock for the z2 "process" and call whatever function begins the shutdown process in Zope? I've looked at simulating keyboardInterrupt, but I'm doubtful about how well it'll work. Ideas?
