New module-wide variables for the PAS and PCS factories. (setup_pcs):
2000-04-25 Federico Mena Quintero <federico@helixcode.com> * wombat.c (cal_factory pas_book_factory): New module-wide variables for the PAS and PCS factories. (setup_pcs): Connect to the "last_calendar_gone" signal of the calendar factory. (last_calendar_gone_cb): Queue a termination job. (queue_termination): Function to queue a termination job. We have to use a timeout to reduce the probability of running into GOAD's race condition with factories. (termination_handler): Check that the PCS and the PAS have zero backends. If so, exit the main loop. (setup_vfs): Use EXIT_FAILURE instead of 1. (init_bonobo): Likewise. (main): Destroy the factories and exit Wombat. Wheee! svn path=/trunk/; revision=2620
