presence processing pins the cpu for hours after joining a large room #5248
Description
for literally hours after joining a large room like HQ, we get stuck in a loop that looks like this:

It makes the server unusable after joining a large room.

this contributes to the general joining-rooms-is-awful of element-hq/element-web#1211 / https://github.com/vector-im/riot-web/issues/2076

oh, I think this might be a dup of element-hq/element-web#5157, since I'm seeing that error repeatedly too. I'd be inclined to fix that and see if this goes away.

well, I think it's better than it used to be. there's still lots of presence; cf element-hq/element-web#3120.
