This doesn't stop the download, since ModalDialog calls
{Get,Wait}NextEvent repeatedly.  BUT if you hold the mouse
down on a menu or scroll bar, the download will be
interrupted.  This is the feature that I think shows the need
for pre-emptive MT most clearly.  MultiFinder is super, given
what it has to do, but I don't like calling $35/hour telecomm
services, and then feeling afraid to scan the menu bar in
another application for fear of wasting valuable download
money.
