20 | # of the inferiors, GDB will try to stop the other inferior, too. So, | |
21 | # a stop request will be sent. Receiving a TARGET_WAITKIND_SIGNALLED | |
22 | # status kind as a response to that stop request instead of a | |
23 | # TARGET_WAITKIND_STOPPED should be handled by GDB without problems. | |
