Interesting, if you are not running a gtk_main() and you are calling:

while ( gtk_events_pending ())
     gtk_main_iteration ();

directly from the audio processing thread then that dramatically changes
things (actually; I couldnt think of a better reason for exposing those
functions from GTK+).

You might consider changing it to do:

/* Prioritize audio processing here */
while ( gtk_events_pending () && audio_probably_wont_skip() )
     gtk_main_iteration ();
