CPU usage when idle

Hi @AlexanderPavlenko ,

Thank you for opening this issue.

It is reproducible to an extent (I need more threads before one of them starts to happily spike).

Although I'm not sure where the math went wrong, it seems to have been caused by an integer overflow in the wind-down timer value (though there should have been a single zero bit there that would protect us in the test value)...

... However I'm not sure if this was the cause because on my computer I've been getting different results and it was harder to reproduce on a 64 bit system (I'm guessing the issue is more pronounced on 32 bit machines as they would have a single bit left before overflow instead of 33 bits left).

Either way, at some point the static_throttle value appears to zero out or otherwise get corrupted.

I pushed a commit with a possible fix. Any change you could test and make sure this solves your issue before I release a patch?

Thanks,
Bo.
