- # This test covers a case where SIGSTOP has been configured to be
- # passed to the target with GDB's 'handle' command, and then a
- # multi-threaded inferior encounters an event that causes all threads
- # to be stopped.
- #
- # The problem that (used) to exist was that GDB would see the SIGSTOP,
- # but decide to ignore the signal based on the handle table.
