I'm running emacs-21.3-12.  It appears that the default behavior is to
title Emacs windows "emacs".  I find it much
handier to title my windows "BUFFERNAME - emacs".
 When I have multiple windows open, this makes it much easier to find
the buffer I am looking for.  I think this may have been the default
at some point back in the Redhat release days; I can't think of a good
reason why it shouldn't be again.

In case it helps make this enhancement easier, let me mention that
I've put the following code in my .emacs file to provide this feature
for myself:

(setq frame-title-format
      (concat  "%b - emacs@" system-name))

Thanks!
