Thanks Tankut.  I've been playing with this.  I'm now convinced that the
approach to make sure that we don't delete the last thread is the best one.
I've been experimenting with it, and I think we're OK wrt the
TARGET_WAITKIND_NO_RESUMED code in infrun.c. I pointed at before.
I've poked at the multi-exit.exp testcase to make it spawn more than
two inferiors, to make sure we always hit the race window, even on slower
systems.  I'm now looking at multi-kill.exp.  I'll have something to
show soon.

Thanks,
Pedro Alves
