bpo-23846: Fix ProactorEventLoop._write_to_self() (GH-11566)
asyncio.ProactorEventLoop now catchs and logs send errors when the
self-pipe is full: BaseProactorEventLoop._write_to_self() now catchs
and logs OSError exceptions, as done by
BaseSelectorEventLoop._write_to_self().

bpo-34323: Enhance IocpProactor.close() log (GH-11555)
IocpProactor.close() now uses time to decide when to log: wait 1
second before the first log, then log every second. Log also the
number of seconds since close() was called.

asyncio: __del__() keep reference to warnings.warn (GH-11491)
* asyncio: __del__() keep reference to warnings.warn

The __del__() methods of asyncio classes now keep a strong reference
to the warnings.warn() to be able to display the ResourceWarning
warning in more cases. Ensure that the function remains available if
instances are destroyed late during Python shutdown (while module
symbols are cleared).

* Rename warn parameter to _warn

"_warn" name is a hint that it's not the regular warnings.warn()
function.

EOF to the reader. See bpo-35065.

bpo-33694: Fix race condition in asyncio proactor (GH-7498)
The cancellation of an overlapped WSARecv() has a race condition
which causes data loss because of the current implementation of
proactor in asyncio.

No longer cancel overlapped WSARecv() in _ProactorReadPipeTransport
to work around the race condition.

Remove the optimized recv_into() implementation to get simple
implementation of pause_reading() using the single _pending_data
attribute.

Move _feed_data_to_bufferred_proto() to protocols.py.

Remove set_protocol() method which became useless.

jhaydaman 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.

Elvis Pranskevichus e2b340ab41 bpo-32751: Wait for task cancellation in asyncio.wait_for() (GH-7216)
Currently, asyncio.wait_for(fut), upon reaching the timeout deadline,
cancels the future and returns immediately.  This is problematic for
when *fut* is a Task, because it will be left running for an arbitrary
amount of time.  This behavior is iself surprising and may lead to
related bugs such as the one described in bpo-33638:

    condition = asyncio.Condition()
    async with condition:
        await asyncio.wait_for(condition.wait(), timeout=0.5)

Currently, instead of raising a TimeoutError, the above code will fail
with `RuntimeError: cannot wait on un-acquired lock`, because
`__aexit__` is reached _before_ `condition.wait()` finishes its
cancellation and re-acquires the condition lock.

To resolve this, make `wait_for` await for the task cancellation.
The tradeoff here is that the `timeout` promise may be broken if the
task decides to handle its cancellation in a slow way.  This represents
a behavior change and should probably not be back-patched to 3.6 and
earlier.

Use transport.set_write_buffer_limits() in sendfile tests of
test_asyncio to make sure that the protocol is paused after sending
4 KiB. Previously,
test_sendfile_fallback_close_peer_in_the_middle_of_receiving() failed
on FreeBSD if the DATA was smaller than the default limit of 64 KiB.
