Dealing with outstanding timeout callbacks

[Braden McDaniel <braden endoframe com>]

I'm writing a Mozilla plug-in which uses g_timeout_add to add a timeout callback
to drive an animation in a widget. In my widget's destroy function, I:

  1. while (gtk_events_pending()) { gtk_main_iteration(); }
  2. Check my stored timeout_id (returned from g_timeout_add): if it is nonzero,
     call g_source_remove.

Yet, there is still an outstanding timeout callback. It runs after my widget is
destroyed, and of course crashes. What do I need to do to run or remove this
callback before my widget is destroyed?
