There was an issue recently with synapse, tbe matrix server implementation, where ram usage would grow until OOM.

The solution was to upgrade Python. But I won't, because that was the problem in the first place, here, apparently.

Oddly if I ran the whole thing under memray with a different allocator, no issue. I say oddly but it isn't.

So I guess my matrix server is broken until I rehome it on a new server with a fresh python instead of 3.10.8.
