it has to do with a lot more than memory, and
considering snap isn't actually using multiple threads, and doesn't really have anything like it, i feel like "thread safe" is just a confusing term to use and that something else should be used. maybe "safe multitasking"?
not malware, but it doesn't do anything if it's not focused, right? it seems like a small performance issue, you should probably disable it for that. it could be part of what's slowing down the moon landing game.
still extremely impractical (unless you can find a smart way to do it) :)
