Spinning ThreadsThere’s a subtle balance to strike here. When a thread runs out of work — its local queue is empty, there’s nothing to steal — should it go to sleep immediately? If it does, and new work arrives a microsecond later, there’s nobody awake to pick it up. Another thread has to be woken from sleep, which costs time. On the other hand, if too many idle threads stay awake burning CPU cycles looking for work that isn’t there, that’s pure waste.
