Could the new gud changes move to a branch?

Are things better or worse after the changes (2004-04-08) that I've just made?
I've removed some constraints for buffer display but maybe there is too much
freedom now.

I don't why its slower unless you are starting with a large disassembly view.
What are the three windows?

I've included this as other debuggers have it but I don't use it myself>
What is it useful for?

The idea behind making "gdb --annotate=3" the default was to get feedback from
others.  Testing it all myself seems a rather sterile approach.

To get the old, simple way all you need to do is set gud-gdb-command-name to
"gdb --fullname" using customise. I've tried quite hard to keep the old
functionality there. Creating a branch for one elisp file doesn't seem
realistic. 

The (last?) remaining problem for GDB-UI seems to be buffer display and this
should be resolved by the time Emacs is released from trunk. If not, then it
will be quite straightforward to reset the default. In the meantime I would
like to keep it as it is to encourage its use in what, after all, is an
experimental version of Emacs.

For debugging emacs in CVS that seems a good idea, in any case.
