bpo-36492: Deprecate passing some arguments as keyword arguments. (GH-12637) 
Deprecated passing the following arguments as keyword arguments:

- "func" in functools.partialmethod(), weakref.finalize(),
  profile.Profile.runcall(), cProfile.Profile.runcall(),
  bdb.Bdb.runcall(), trace.Trace.runfunc() and
  curses.wrapper().
- "function" in unittest.addModuleCleanup() and
  unittest.TestCase.addCleanup().
- "fn" in the submit() method of concurrent.futures.ThreadPoolExecutor
  and concurrent.futures.ProcessPoolExecutor.
- "callback" in contextlib.ExitStack.callback(),
  contextlib.AsyncExitStack.callback() and
  contextlib.AsyncExitStack.push_async_callback().
- "c" and "typeid" in the create() method of multiprocessing.managers.Server
  and multiprocessing.managers.SharedMemoryServer.
- "obj" in weakref.finalize().

Also allowed to pass arbitrary keyword arguments (even "self" and "func")
if the above arguments are passed as positional argument.

bpo-33716, test_concurrent_futures: increase timeout (GH-7828) 
Increase the timeout from 1 min to 5 min.

Replace also time.time() with time.monotonic() for timeouts.

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.

c4b695f85e bpo-33097: Fix submit accepting callable after executor shutdown by interpreter exit (GH-6144) 
Executors in concurrent.futures accepted tasks after executor was shutdown by interpreter exit. Tasks were left in PENDING state forever. This fix changes submit to instead raise a RuntimeError.

94459fd7dc bpo-31699 Deadlocks in concurrent.futures.ProcessPoolExecutor with pickling error (#3895) 
Fix deadlocks in :class:`concurrent.futures.ProcessPoolExecutor` when task arguments or results cause pickling or unpickling errors.
This should make sure that calls to the :class:`ProcessPoolExecutor` API always eventually return.

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.

489d91c61d bpo-31249: test_concurrent_futures checks dangling threads (#3167)

dangling threads and processes on all tests, not only tests using
ExecutorMixin.

3df9dec425 bpo-30845: Enhance test_concurrent_futures cleanup (#2564) 
* bpo-30845: reap_children() now logs warnings

* bpo-30845: Enhance test_concurrent_futures cleanup

In setUp() and tearDown() methods of test_concurrent_futures tests,
make sure that tests don't leak threads nor processes. Clear
explicitly the reference to the executor to make it that it's
destroyed (to prevent "dangling threads" warning).

a3d91b43c2 bpo-29212: Fix the ugly repr() ThreadPoolExecutor thread name. (#2315) 
bpo-29212: Fix the ugly ThreadPoolExecutor thread name.

Fixes the newly introduced ugly default thread name for concurrent.futures
thread.ThreadPoolExecutor threads.  They'll now resemble the old <=3.5
threading default Thread-x names by being named ThreadPoolExecutor-y_n.
