| # 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. |
