gh-110335: asyncio test_unix_events cleans multiprocessing (#110336)
test_unix_events tests using the multiprocessing module now call
multiprocessing.util._cleanup_tests().

gh-110088: Fix asyncio test_prompt_cancellation() (#110157)
Don't measure the CI performance: don't test the maximum elapsed
time. The check failed on a slow CI.

gh-110088, gh-109878: Fix test_asyncio timeouts (#110092)
Fix test_asyncio timeouts: don't measure the maximum duration, a test
should not measure a CI performance. Only measure the minimum
duration when a task has a timeout or delay. Add CLOCK_RES to
test_asyncio.utils.

gh-109833: Fix asyncio test_wait_for() (#109834)
Expect the test to be "short" but don't measure the exact performance
of the CI. SHORT_TIMEOUT is about 30 seconds whereas the cancelled
coroutine takes around 1 hour.

gh-109709: Fix asyncio test_stdin_broken_pipe() (#109710)
Replace harcoded sleep of 500 ms with synchronization using a pipe.

Fix also Process._feed_stdin(): catch also BrokenPipeError on
stdin.write(input), not only on stdin.drain().

gh-109582: test_fork_signal_handling should wait for event (#109605)
Sometimes the child_handled event was missing because either
the child quits before it gets a chance to handle the signal,
or the parent asserts before the event notification is
delivered via IPC.  Synchronize explicitly to avoid this.

gh-108973: Fix asyncio test_subprocess_consistent_callbacks() (#109431)
SubprocessProtocol process_exited() method can be called before
pipe_data_received() and pipe_connection_lost() methods. Document it
and adapt the test for that.

Revert commit 282edd7b2a.
_child_watcher_callback() calls immediately _process_exited(): don't
add an additional delay with call_soon(). The reverted change didn't
make _process_exited() more determistic: it can still be called
before pipe_connection_lost() for example.

gh-109295: Clean up multiprocessing in test_asyncio and test_compileall (#109298)

gh-103793: Defer formatting task name (#103767)
The default task name is "Task-<counter>" (if no name is passed in during Task creation).
This is initialized in `Task.__init__` (C impl) using string formatting, which can be quite slow.
Actually using the task name in real world code is not very common, so this is wasted init.

Let's defer this string formatting to the first time the name is read (in `get_name` impl),
so we don't need to pay the string formatting cost if the task name is never read.

We don't change the order in which tasks are assigned numbers (if they are) --
the number is set on task creation, as a PyLong instead of a formatted string.

gh-83925: Make asyncio.subprocess communicate similar to non-asyncio (#18650)
subprocess's communicate(None) closes stdin of the child process, after
sending no (extra) data. Make asyncio variant do the same.
This fixes issues with processes that waits for EOF on stdin before
continuing.

GH-84559: Deprecate fork being the multiprocessing default. (#100618)
This starts the process. Users who don't specify their own start method
and use the default on platforms where it is 'fork' will see a
DeprecationWarning upon multiprocessing.Pool() construction or upon
multiprocessing.Process.start() or concurrent.futures.ProcessPool use.

See the related issue and documentation within this change for details.

gh-100160: Restore and deprecate implicit creation of an event loop (GH-100410)
Partially revert changes made in GH-93453.

asyncio.DefaultEventLoopPolicy.get_event_loop() now emits a
DeprecationWarning and creates and sets a new event loop instead of
raising a RuntimeError if there is no current event loop set.

gh-93453: No longer create an event loop in get_event_loop() (#98440)
asyncio.get_event_loop() now always return either running event loop or
the result of get_event_loop_policy().get_event_loop() call. The latter
should now raise an RuntimeError if no current event loop was set
instead of creating and setting a new event loop.

It affects also a number of asyncio functions and constructors which
call get_event_loop() implicitly: ensure_future(), shield(), gather(),
etc.

DeprecationWarning is no longer emitted if there is no running event loop but
the current event loop was set.
