Great to hear, thanks for giving it a try.  io-stalls-6 helped most when
you've got multiple devices and a streaming write to one was slowing
down all the others.  -7 added in a tweaked form of Andrea's elevator
latency fixes, and they make a big difference when there's a lot of
writes to the drive you're trying to read from.

Hopefully we'll be able to hash out something suitable for 2.4.22-pre.
