That's a bit of a non-answer. I'm fairly sure its not a gazillion issues, since the actual scheduler tick doesn't actually do that much.

So start by enumerating what is actually required.

The 2), which I suppose you're now trying to implement is I think entirely the wrong way. The tick really assumes it runs local, moving it to another CPU is insane.

Yeah, I was trying this one :(

I still don't have enough knowledge of scheduler and so can't exactly tell what all requires tick to fire a 1 second.

@Frederic: Can you please help :) ?
