* Close explicitly queues to make sure that we don't leave dangling
threads
* test_queue_in_process(): remove unused queue
* test_access() joins also the process to fix a random warning
bpo-26762: test_multiprocessing now detects dangling processes and
threads per test case classes:
* setUpClass()/tearDownClass() of mixin classes now check if
multiprocessing.process._dangling or threading._dangling was
modified to detect "dangling" processses and threads.
* ManagerMixin.tearDownClass() now also emits a warning if it still
has more than one active child process after 5 seconds.
* tearDownModule() now checks for dangling processes and threads
before sleep 500 ms. And it now only sleeps if there is a least one
dangling process or thread.
bpo-26762: Fix more dangling processes and threads in
test_multiprocessing:
* Queue: call close() followed by join_thread()
* Process: call join() or self.addCleanup(p.join)
test_level() of _test_multiprocessing._TestLogging now uses regular
processes rather than daemon processes to prevent zombi processes
(to not "leak" processes).
* bpo-26732: fix too many fds in processes started with the "forkserver" method
A child process would inherit as many fds as the number of still-running children.
* Add blurb and test comment
* bpo-19896: Add typcodes 'q' and 'Q' to multiprocessing.sharedctypes. Patch by Antony Lee.
* Add NEWS entry.
* Slightly tweak NEWS entry
Make it clear this is more of a fix rather than a new feature.
* bpo-30794: added kill() method to multiprocessing.Process
* Added entries to documentation and NEWS
* Refactored test_terminate and test_kill
* Fix SIGTERM and SIGKILL being used on Windows for the tests
* Added "versionadded" marker to the documentation
* Fix trailing whitespace in doc
* Clear potential ref cycle between Process and Process target
Besides Process.join() not being called, this was an indirect cause of bpo-30775.
The threading module already does this.
* Add issue reference
* Fix bpo-30596: Add close() method to multiprocessing.Process
* Raise ValueError if close() is called before the Process is finished running
* Add docs
* Add NEWS blurb
* bpo-24484: Avoid race condition in multiprocessing cleanup
The finalizer registry can be mutated while inspected by multiprocessing
at process exit.
* Use test.support.start_threads()
* Add Misc/NEWS
* bpo-30414: multiprocesing.Queue._feed do not break from main loop on exc
Queue background running thread was not handling exceptions correctly.
Any exception occurred inside thread (putting unpickable object) cause
feeder to finish running. After that every message put into queue is
silently ignored.

* bpo-29861: release references to multiprocessing Pool tasks
Release references to tasks, their arguments and their results as soon
as they are finished, instead of keeping them alive until another task
arrives.
* Comments in test
* multiprocessing: open file with closefd=False to avoid ResourceWarning
* _test_multiprocessing: open file with O_EXCL to detect bugs in tests (if a
previous test forgot to remove TESTFN)
* test_sys_exit(): remove TESTFN after each loop iteration
Initial patch written by Serhiy Storchaka.
