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.

Allow re-writing parity on a RAID 0 to trivially succeed, and to set the

Disallow interrupting parity re-writes or copybacks by removing PCATCH

from the tsleep()'s (they probably shouldn't have been there in the
first place!). Making parity re-writing and copybacks interruptable
will require re-designing how a few things are done (e.g. how memory
is freed for structures shipped off to routines that run asynchronously
relative to the calling routine). Fix a few other tsleep's while we're at it.

Make it so raidframe will only perform synchronous writes, and async
...
reads. This avoids a problem where many writes will cause the driver
to allocate way too much memory.
This needs to change to a queueing system later, which will provide a
way to limit the memory consumed by the driver.
Without these changes, raidframe would use 24M or more on my machine when
the buffer cache dumped all its dirty blocks. Now it uses around 200k
or so.
