Please remind me, why was this a desirable capability again?

Personally, I can't imagine someone would really want to do this using
the traditional gdb CLI, at least not within a single gdb instance.
I'd simply fire up two (or more) xterms and debug the processes
seperately.  One thing that could be useful though for that scenario
is the ability to hand of processes between gdb instances upon

I suppose multiprocess debugging makes somewhat more sense in a
GUI-based IDE environment.  But running multiple instances of gdb
should work just as well in that case.

Adding a "multiprocess" capability to GDB is almost certainly going to
add significant complexity.  So there should be a good motivation for
