Yeah, this is one of those places where we wish the target stack was
actually as flexible as it was envisioned to be.
Once we get a tracepoint-supporting gdbserver, perhaps someone can just
try the experiment of creating a tfind target. It might not need
anything more hairy than some explicit calls down into the target stack,
for instance to read memory using the target that is actually storing
the collected data.
I can see users really really liking it if resumption commands were to
work and do the expected things - and now we have reverse execution
commands that could be used to find previous trace frames....
