I actually think the last dma patch I saw was addressing the problem in
the wrong way.
IIRC, it was using threads? We really ought to do the work to make the
block API properly asynchronous. It may seem tedious now, but it would
also allow the use of something like linux-aio down the road which has the
potential to have a pretty huge performance impact on block performance
(with pbrook's recent SCSI emulation).
