But at some point we make the image read-only, and at that point there
are still other servers running.  If other servers are running, they use
some pagers.  Iirc if a library is in use (i.e. a pager is in use) at
system shutdown, we get those 'deleted inode has X links(?), should be
zero' issues.  And these do pile up.
