Like Rui said, thanks!

How hard would it be to convert vnd to use direct I/O?  It seems like
that would fix some annoying double-caching problems (and a lot more
people actually use vnd on production systems now because it is a
convenient backing store for Xen virtuals).

If it's just mechanical changes, let me know what they are, and I will
have a shot at it if I can find the time this weekend.
