We need aiomcache to be updated to have aiohttp-session working on 3.10+.

Seems the repo has been untouched for 4 years though. I made a start on some fixes at: aio-libs/aiomcache#207
Although, this seems to be one of the repos I don't have maintainer access to.

@Dreamsorcerer added you as aiomcache maintainer.

I'll try to find time for review tomorrow.
Have too many things that require my attention, sorry.

Now blocked on #663. Hopefully will be good after that.
