	I'm not sure there is a reliable way to detect when an application has
finished startup. Perhaps the first time the main loop goes idle would
be a good indicator but I think you have difficulty distinguishing
between that case and the case of the app blocking on the result of a
CORBA call.

	To give you an idea of where a GNOME application starting up spends its
time see this:

http://mail.gnome.org/archives/desktop-devel-list/2004-April/msg00360.html

	The only things really specific to the panel in this is the loading of
main menu and applets/launchers.

Cheers,
Mark.
