Idle Function Not Getting Called

[Marshall Lake <mlake mlake net>]

What stops an idle function from being executed? ... pending events, 
right?

I have a situation where an idle function does NOT get called with the 
following code:

    g_idle_add ((GSourceFunc) idlefunc, NULL);

OR

    while (gtk_events_pending ())
        gtk_main_iteration ();
    g_idle_add ((GSourceFunc) idlefunc, NULL);


However, the idle function gets called fine with the following code:

    g_idle_add ((GSourceFunc) idlefunc, NULL);
    while (gtk_events_pending ())
        gtk_main_iteration ();


What would account for such behavior?

Additionally, in the third code snippet, program flow gets stuck in the 
while loop until the idle function removes itself by returning FALSE.
