    Oh, scratch that comment.  You were trying to get the path to the
    file VN was covering.

    Use vn_fullpath() and pass 'curproc' as the process, though, instead
    of cache_fullpath(), and note that it might fail (maybe have it print
    '?' for the filename if it fails).  If the process is non-NULL
    vn_fullpath()/cache_fullpath() will truncate the path properly to
    the process's chroot.
