Your diagnosis appears to be correct. I checked in what I think
should be a fix.
I remember thinking once before that we weren't releasing the editor
and listener windows when they were closed, but I somehow convinced
myself that we actually were. I must have been mistaken.
One thing I'd like to point out is that listeners have an autorelease
pool. This way, you can say stuff like (#/orderedWindows *nsapp*),
and not have the returned object evaporate out from underneath you.
There's a top-level command ":rap" which will drain the autorelease
A potentially confusing side effect of this is that if you do (#/
orderedWindows *nsapp*), close a document window, and then do (#/
orderedWindows *nsapp*) again, you'll see the closed window still in
the list. This is because the window is still retained by the NSArray
that the first call to #/orderedWindows returned. If you do :rap, and
then do the (#/orderedWindows *nsapp*) again, the window should be gone.
