Check out the patch I just sent out to fix the JACK shutdown issues, 
which should take care of phasex shutting down in an unfriendly way 
when this happens.

I'll be looking into the patch loading issue next.  From what I can
tell, the first access of the File menu (either by hitting it
directly or accessing an item through a keyboard acceleration)  
causes enough of a CPU hit to disrupt other threads.  This is the
only menu that currently uses the GTK stock items and keyboard
accelerations.  Any GTK hackers out there have any tricks for making 
sure a GtkAccelGroup has fully initialized itself?
