It's GSoC project, see http://emacswiki.org/emacs/GDB-MI/ for some
details. Don't wait, report bugs of Emacs trunk version as soon as you
encounter them, but _please_ file *different* reports for different
bugs.

I first put really bleeding changes to my Mercurial repo, then commit
them to Emacs upstream for further testing. Non-stop debugging support
will hit the trunk by the end of this week.
