One weird trick for better performance
@thezoq2 meanwhile at work: my dude we're already spawning 320 threads

@thezoq2 why 320 when it's 64 cores?

well it's 128 HW threads.

...wait, why 320 though?

look stuff on the thread pool was waiting for work to finish on other threads, and that got deadlock-y, so we just added another thread pool

...wait, why 320 though?

@thezoq2 (FWIW, no that's not the actual reason, there actually is 2 128-thread pools and stuff in category A must not depend on stuff in category B for deadlock reasons, but the other 60+ threads are just there because other things love to spawn a thread or 10 or 40 too)
