A different possibility would be to change focus visibly, but when the
mouse pointer moves out of the window and, for example, onto toolbar
or menu bar, refocus back to the original window if no intervening
event occured.

This would imply that you could not change focus only by moving the
mouse if the first action in the new window was using the toolbar or
menu bar.  It would also mean quite more flicker than the "just
unfocus" variant.
