So does that give people who write allocators license to to threads arbitrarily? More seriously, in C++ apps (Games financial trading etc...) it is common enough to need to carefully manage memory to get that last bit of performance even after saturating all the CPUs and GPUs. Superficially your advice makes sense. Going forward I think I might leave threads in the same mental bucket as allocators and see if that heuristic holds up.
