Fixes #1491
This fixes UB with the
USED_PARALLELISMvariable, rationale described in #1491. Additionally,static mutis difficult to use correctly, to the point where it is likely to be removed in a future edition. Instead, I have replaced theboolwith anAtomicBool, which can be used without unsafe.This approach is superior to #1492, as using a mutex for a bool is wasteful.
