Making session startup wait for an application to exit

[Kevin Oberman]

Is there any way to add an application to the startup so that the
startup will block until that application is complete?

It seems like it does this for some of the internal apps (like nautilus
and gnomepanel), but I don't see a way to make it wait for an
application I want to run to completion before my session is started.
