Yeah.

I'm just brainstorming different scenarios to try to understand what
problems multi-target might have.  Running a new program via an
extended-remote gdbserver seems like a reasonable thing to want to do;
but I wasn't sure of the mechanics.

Yeah, that may be the way to go.

Or maybe "always reuse" is best?  Since it seems unlikely to want to
open multiple concurrent connections to the exact same server/port pair.
(I guess it could work with some hypothetical gdbserver.  But I don't
think it exists.)

I was just thinking something like:

(gdb) info inferior
  Num  Description       Executable        Target
* 1    process 2994      /usr/bin/gdb      native
  2    process 1222      /bin/sh           server:9999

IT sets were the answer to this in the past, but I see in your other
mail that you also wanted it to show up in "info inferiors".  That seems
reasonable to me; though maybe it could be some kind of itset flag.

I think Pedro and Yao have the best status on itsets.
