Ideally there'd be both behaviours: * You'd specify whether a timer/sleep needs to be exact or can withstand some jitter (which is what linux provides); and * You can communicate to the kernel its aggressiveness for coalescing wakeups.
Teaching powerd to flip on/off a sysctl for this isn't that tricky. I remember seeing someone else in #bsdmips having issues figuring out sleep-in-kernel durations and it being exactly this stuff (and it being you, Ian, that figured it out) - so I'd like to at least fix it in -head this time around! Also - I thought the other issue was that precise callouts (versus the default for callouts now which is "fuzzy" unless you specify precision) were still jittering. Is that the case?
