Several tests have this racy issue with gdbserver.  It'll usually manifest when
running the main thread to exit while there are still other threads running.
Notice how the test program doesn't gracefully terminate/join all threads
before exiting.  So gdb/gdbserver are processing something for one thread,
and meanwhile the process exits.  This is really the same as PR 18749.
