* bpo-26762: Avoid daemon process in _test_multiprocessing (#2842)
test_level() of _test_multiprocessing._TestLogging now uses regular
processes rather than daemon processes to prevent zombi processes
(to not "leak" processes).
(cherry picked from commit 06634950c5)
* test_multiprocessing: Fix dangling process/thread (#2850)
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)
(cherry picked from commit d7e64d9934)
* test_multiprocessing detects dangling per test case (#2841)
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.
(cherry picked from commit ffb49408f0)
* bpo-26762: test_multiprocessing close more queues (#2855)
* 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
(cherry picked from commit b4c52966c8)
* bpo-31019: Fix multiprocessing.Process.is_alive() (#2875)
multiprocessing.Process.is_alive() now removes the process from the
_children set if the process completed.
The change prevents leaking "dangling" processes.
(cherry picked from commit 2db64823c2)
* 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.
(cherry picked from commit 79d37ae979)
* 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

multiprocessing: Process._bootstrap() keeps a reference to the old process to
delay its finalization until after _run_after_forkers() as been executed. This
change should fix a crash on Mac OS X Tiger when a lock is released after a
fork.
