[issue29517] "Can't pickle local object" when uses functools.partial with method and args...

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Since WeakSet never was pickleable, the difference perhaps in the use of WeakSet in asyncio. BaseEventLoop contains a WeakSet attribute since 3.6, this makes it non-pickleable.

I'm not sure this is a cause of the failure.
