The site is down, but I will take a look when I can.  I was in fact using growl, 
but never got beyond this.  I wound up aliasing a few commands to run growl-notify.
I wouldn't mind a general solution, as growl probably isn't going to disappear.

You suspected correctly.  (2) worked like a charm, and am embarrassed since I read that chapter in your book last night.

I'm still trying to figure out how to do (1) in some reasonably elegant manner. I'm using iTerm, since it is a bit more amenable to zsh scripting control than terminal, and it in fact has a built-in growl notification, but it is overkill, so I wind up turning it off.

Maybe I am taking a stupid approach.  What would be ideal is if a user could specify a time in seconds beyond which the notification would be issued.  I am most interested in this for processes that take minutes to hours, rather than a few seconds to run in the foreground, and it would also be nice for background processes as well.

Thanks for setting me on the right track.
