I assume that we agree that the 'run' command is not supported in target
remote mode.

Maybe a better way to have stated this would be that follow-exec-mode is
of limited used in target remote mode, since the 'run' command is not
supported.  The point being that the main reason a user would want to
set follow-exec-mode would be to get control over which inferior is run
when a 'run' command is executed.

I have to admit that it is incorrect to say that it is unsupported,
since setting follow-exec-mode *will* control whether a new inferior or
the same inferior is used for the execed program.  But there isn't much
you can do differently without the 'run' command.  Using
follow-exec-mode 'new' there *is* a record of what programs have been
run, which could be useful.

Is that a more accurate description, or am I misunderstanding something?

I'll get to work on the rest of this, hopefully sometime next week.
thanks
