Slightly off subject, but I plan to sometime carry the vnode/offset
caching to a more generalized scheme that also encompasses device/offset
caching.  Specifically, device/offset is the same as vnode/offset.

This will allow us to cache data without the vnode.  However, we will
continue to have the advantages of the current vnode/offset scheme.
