[issue27585] asyncio.Lock deadlock after cancellation

[Alexey Popravka]

Alexey Popravka added the comment:

Hi guys! Any update on this?
I've just hit this issue.
Cancelled futures in _waiters is not a problem (any more).

There is still a problem when release() wakes up next waiter
but task waiting for it gets cancelled and so all the rest waiters
are in pending state forever.
I've attach one more test to reproduce this issue.

[issue27585] asyncio.Lock deadlock after cancellation

Alexey Popravka added the comment:

Also there is the same problem with asyncio.Condition wait() / notify() couple 
as it repeats the same Lock.acquire()/release() logic
