[issue44318] Asyncio classes missing __slots__

[Andrei Kulakov]

Andrei Kulakov <andrei.avk at gmail.com> added the comment:

The size of an instance of Semaphore is 48, of an empty tuple is 40, of a small int is 28, of an instance of a normal class with a single slot in __slots__ is also 40, are you use 48 byte size will really be an issue for you?
