You don't want two modal dialogs in a desktop anyway as they give very bad
user experience. So queing _them_ would be fine for me, but of course it's 
unacceptable to stall progress displays while a modal dialog is open.

I see another problem with such "out of process" dialogs though and that is 
dualhead. Everywhere where we use that, it's causing problems: e.g. cookie 
dialogs appear on wrong desktop/screen.
