Yeah, no.  That would just paper over problems.  GDB should cope with threads disappearing beneath it, as they're resumed, stopped, etc.  Forcing scheduler-locking just
means you're only resuming one thread instead of many, and thus reducing the chances of some GDB issue triggering.  Wouldn't be much different from making the testcase
be single-threaded.
