I don't think it's worthwhile (even with the current algorithm where it's easy
to account for p).
I suspect you are right, it's marginal.

't see why it should do this. It would make more sense
to just leave the current request in the queue, and let end_request
deal with dequeueing when it is done.

the ordering algorithm), tiotest performance drops significantly in the
2-thread-reading case. elvtune settings doesn't matter, that's only a matter

AFAIR, Eric tried to talk to the Compaq folks (and Leonard too, I dunno)
