There is probably a few things that assume local calls but last time I checked I had the impression that it was fairly possible to call sched_class::task_tick() remotely. rq is locked, no reference to "current", use rq accessors...

OTOH scheduler_tick() itself definetly requires local calls.

possible isn't the problem, its completely insane to do that.
