Starting XUL from JavaXPCOM

Hi all,

I've managed to get JavaXPCOM to create and run an xul window, but I'm 
using nsIAppStartup to do so, and when I call run(), it blocks, and 
JavaXPCOM doesnt seem to like being called from other threads... so, 
presumably, we need a way of hooking into the run() loop, or 
implementing the loop myself.  Does anyone have any pointers?  I'm 
looking through the Mozilla plugin for eclipse source, but can't really 
see how its supposed to work.

Any pointers would be most welcome.
