from a quick look at your source, I got the impression what you are 
doing is essentially:

gboolean 
timeout_event (gpointer data)
{
  gtk_timeout_add (delay, timeout_event, data);
  return TRUE;
}

int
main (void)
{
  gtk_timeout_add (delay, timeout_event, data);
  gtk_main();
}


this will of course eat all your CPU and memory since you adding a
new timeout each time the timeout_event is handled. The number of
timeouts registered to the main loop goes up exponentially. I'd
suggest you read http://gtk.org/tutorial/ch-timeouts.html#SEC-TIMEOUTS

Then, consider using g_timeout_add() from GLib directly instead of 
the GTK wrappers.


Salut, Sven
