Actually, I think that's mostly me being confused and taking others with
me ;-)
It's definitly a problem, and we have a solution there. The one thing
I'm still a bit concerned about is: Do we need a CHECK_FOR_INTERRUPTS,
and do we need an upper limit on the spinning. In theory we can spin
with 100% CPU usage, which is not good. So we should either spin a
limited amount of times, or we should perhaps introduce a tiny delay?
