Yeah, it's a current limitation. I've looked at this a
bit after Tom reporting some other multi-process breakage, and
it didn't look like a quick fix. You may not need that
against linux gdbserver since it allows reading/writing
memory even when threads are running, while native linux gdb
doesn't. We're likely to get to fix all of this for
proper ptsets/itsets support (which we'll be starting
on real soon).
