My vague notion was that we'd get it working well enough to have basic
parity with native or gdbserver on some realish test cases, and then just
look at the protocol interaction log to see cases where we could reduce
round-trips between gdb and the stub. Some of those are bound to entail
protocol extensions and gdb changes to exploit them. Off hand, the Z cases
might be the only things that won't need that.
Thanks,
