What I described happens with your path installed just the same, so it  
is really only part of the problem.

One issue I can see there in NS is that NS hides frames by moving them  
behind the desktop in the view hierarchy, so raising them implies  
making them visible.  Of course we could (and should) add a check for  
frame visibility to the appropriate NS functions.

As far as I remember, raising implied making a frame visible in Emacs  
22/Carbon.

I'm not sure if a change to the behavior of raise-frame would be a  
good idea at this stage; the bug at hand needs fixing of course.
