Isn't that going to cause all kinds of confusion when the child process is trying to re-use the same socket FD to talk to the X server and such? I don't have a big objection to marking every module as permanently resident. I just needed to know whether that was a technical requirement or not. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
