	This is principally, I think, because there is only one socket
connection to the X server.

	Please don't take this as an insult in any way, but isn't this
statement a tautology?  Isn't the question "How can we optimize for
single-processor use only and also be optimized for multi-processor use"?
	I personally like it this way, since I can group the gdk_threads
calls around sections of gdk code, and I don't have to constantly lock and
unlock the mutex while doing things.  Granted, it's not the biggest
performance hit to have 2/3 of every gtk/gdk call being a mutex function,
but it's not the most wonderful method of doing things either.

	unfortunately I don't quite follow this.

	Btw, shouldn't this discussion be on gtk-devel@redhat.com, not on
the gnome devel list?
