This is going to be pretty imprecise, since there are only 11 possible values of sleeptime_ms. Can you switch the timer and CPU_THROTTLE_TIMESLICE to nanosecond precision instead? It's okay to provide this as a patch 6/5, and the maintainer will squash it into this patch. Alternatively this can be sent as v7, as you prefer.
