I don't think we would want to always use it, since it would disturb caches and increase latency for restarting user processes. Perhaps it should only start up after the system has been idle for a while (this means 1/HZ or 2/HZ in practice unless idle() spins testing the time, and 10-20 ms may be good in theory too because it is similar to disk seek times).
