You're thinking single-inferior. What about threads of different inferiors
behind a single target_ops? Say, you're attached to process A, but you're
leaving it running (you'll hit internal breakpoints in forward mode),
while you're debugging/inspecting process B in reverse. There you have
your two threads, on a single target, where the single per-target
direction flag stops making sense.
I understand the idealism behind this. I just posted the patch
to show the direction I think we will end up taking, instead of
trying to explain it by: "it would be nice if you did it the way
I'm saying".
