a94ee12c26 bpo-34819: Use a monotonic clock to compute timeouts in concurrent.futures (GH-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.

0a28c0d12e bpo-33238: Add InvalidStateError to concurrent.futures. (GH-7056) 
Future.set_result and Future.set_exception now raise InvalidStateError
if the futures are not pending or running. This mirrors the behavior
of asyncio.Future, and prevents AssertionErrors in asyncio.wrap_future
when set_result is called multiple times.

574562c5dd bpo-31641: Allow arbitrary iterables in concurrent.futures.as_completed() (#3830) 
This was possible before.  GH-1560 introduced a regression after 3.6.2 got
released where only sequences were accepted now.  This commit addresses this
problem.

97e1b1c814 bpo-27144: concurrent.futures as_complete and map iterators do not keep reference to returned object (#1560) 
* bpo-27144: concurrent.futures as_complie and map iterators do not keep
reference to returned object

* Some nits.  Improve wordings in docstrings and comments, and avoid relying on
sys.getrefcount() in tests.

7462b64911 Issue #25523: Correct "a" article to "an" article 
This changes the main documentation, doc strings, source code comments, and a
couple error messages in the test suite. In some cases the word was removed
or edited some other way to fix the grammar.
