we couldn't find any reason th have block devices except in teh case for
exporting the nodes via NFS.
The buffer caching is done at teh filesystem level, and raw-io is faster
with the raw device, so it was complicating the code without giving us any
real advantage.. If you need a cached device then you can achieve that in
other ways.
your comments are appreciated..
