bpo-34819: Use a monotonic clock to compute timeouts in concurrent.futures #9599

Thanks for doing this! This looks good on the principle. Note however that the I think the NEWS message deserves improving a bit, I will edit it if you don't mind. |

(given the above, did you check this PR solves the issue with your script, btw?) |
I'd be glad if you did, it probably does need some clarification.
I double-checked to make sure and it indeed fixes it. |

…tures (pythonGH-9599) Use a monotonic clock to compute timeouts in :meth:`Executor.map` and :func:`as_completed`, in order to prevent timeouts from deviating when the system clock is adjusted. This may not be sufficient on all systems. On POSIX for example, the actual waiting (e.g. in ``sem_timedwait``) is specified to rely on the CLOCK_REALTIME clock.
