I've seen stuff on FASTPOLL, but have no idea what it does. We're still
considering turning on affinity.

That's my understanding, but I can't find any evidence of this. As I
said, idle time runs high (>60%), and wio is always < 1%. This is why I
can't reconcile the ready queue with the high idle time. Although, to
be fair, there are rarely more than about a dozen threads on the ready
queue. Still, if idle time is that high, I wouldn't expect to see much
of ANYTHING on the ready queue.
