Actually, I avoid trying to do anything extensive or critical upon closure of a
window, whether browser or application.  I consider it a usability irritant, since
the user may be trying to shut down their system, or in the middle of an
emergency.  Whenever possible, do as much of your cleanup/logout/pre-logout as you
can along the way, and also design your application to come back up in a sane
useful state if it was shut down suddenly, say due to a system crash or lockup.
(I've heard those happen every once in awhile...)

That said, yes, onunload is not reliable.  If you think you will usually or often
have to display a logout window, bring it up beforehand, but keep the focus on the
main window.  If the user does an orderly logout from the main window, close the
other one.  If they just close the main window, the logout window is there to
finish the job.
