Log Message:
Once upon a time, long long ago, there was a "fix" added to the
RAIDframe driver to stop it from eating too much kernel memory when
writing data.  But that fix had a nasty side-affect of hurting write
performance (*much* more than I thought it would).  These changes nuke
that "fix", and instead put in a more reasonable mechanism for limiting
the number of simultaneous IO's which can be happening for each RAID device.
The result is a noticeable improvement in write throughput.  The End.
