Whatever I asked to be debugged. Could be perl's, mdb, bashdb, pydb
and/or gdb. As I look at my emacs buffer list, I see all of them in
use right now. The two gdb sessions debug different programs and have
different breakpoints set for each -- different gdb states (file args,
etc.), and that is true in other debuggers when I debug multiple
programs.

If you're trying to be diadactic, give it up. I wrote "Currently I
have no problem having serveral GUD sessions", and just take that at
face value. No doubt there are subtleties I'm missing and perhaps when
you add into GNU Emacs in whatever it is you are clearly conveying (to
others), feeble me will see the light and marvel at it.

I'm still down at the level where I am trying to understand where/when
the "local-set-key" of the "menu-bar" keymap makes itself evident to
users. ;-)

Okay.

By all means -- GO FOR IT! I'm assuming these changes you envision
will at least solve the set of issues that have been troubling me.

Thanks for volunteering to take this on.
