    It survived my overnight test, which I find quite amazing considering
    what I just ripped out and replaced!  In fact, the patch is running
    better then HEAD is.

    I did notice that it does not pick up on NFS server-side file changes.
    If the DFly client running this patch has a negative cache entry for
    a file, and the file is created by the server, the DFly client doesn't
    pick up on it.  Even unmounting and remounting doesn't work, so my 
    unmount-time cache purge isn't working.  I have some cache invalidation
    work to do :-)

    I am going to fix VOP_CLOSE and fix the cache timeouts and unmount-time
    invalidation issues and come up with another patch set.  If that one works
    I'll commit it to HEAD and move on to the next step.
