As it stands, Emacs is unable to consistently hide all frames, and  
this behavior of unhiding frames is simply not documented as such.

If it is the window manager that makes a frame visible, then we should  
respect that.  It's not our business.  But forcefully un-hiding some  
other frame as is done specifically in NS is not a great idea.  (We  
can select a frame without unhiding it!)

Hiding a frame is the only workaround that I know that allows me to  
remove all frames.  Running an application without any open frames is  
a perfectly normal thing to do in any environment that displays the  
menu bar on the top.  The code can't handle deleting the last frame  
(as it is assumed in many places that there is a live, selected  
frame).  That's why hiding is important to me.
