I was thinking of a scenario like: I have an existing connection to an
extended-remote target, then I want to add an inferior and then run it
on that target.

I guess something like this would work if "target extended-remote"
always did connection sharing:

    add-inferior -exec whatever
    target extended-remote server:port
    run

The issue I have is differentiating this from the scenario of: add
inferior, connect for the first time, then try to run.  Won't this do
something different if the remote is already running?

I feel like I'm confused somehow.

David> . you want to know the full set of inferiors and their targets.

David> Seems somewhat esoteric.  Perhaps a maint command would be appropriate?

I suppose we could just print it in "info inferiors".
