I think it would be nice from a GDB point-of-view, so, it would be nice
if someone from the community would step up :-)

I had also imagined this as multi-process.  You have a bunch of linux
processes already running and you can attach to multiple ones.
Like, say, vi and emacs.  So, multi-process debugging would work for
long-lived processes.

I thought multi-program would launch different programs, which could
then be short-lived.  But that's how I imagined it...
