.. I'm pretty damned sure we're going to need to enforce a "never earlier than X" latency. Is there a more detailed writeup of calloutng somewhere, besides David's slides? The wiki page is rather empty. Eg - I think this work does coalesce wakeups, right? Or it can? So when in low-power scenarios you can end up with lower-resolution callout periods, but many less CPU wakeups a second? (Do we actually _expose_ wakeups-per-second somewhere?) Adrian
