:Actually, that ties into the one open question for me:
:Given the file descriptor table, how do I map files/vnodes back to
:the absolute path of the file that they reference?
:If anyone knows off hand how to do it, or that it can't be done,
:please chime in. You'll save me at least an hour of mucking around.
:>     Anyway, this sounds ilke a really good idea!  :-)

    This will be possible after my namecache changes, but even with that
    ability you will still need to record the inode number and filesystem
    device as a validator.  For now the inode number & filesystem device
    (as returned by fstat) should have enough info for a primitive file
    reattachment even though you might have to search a filesytem mount
    to locate the file(s).
