    It seems to happen perhaps 20-25 percent of the time and after it
    happens the zone is "infected" until system reboot.

    If it matters, I am using lightly-loaded 8-core, 16-thread Xeon-D
    hardware.

    Interestingly, I just noticed that my most recent effort (cribbed from
    OmniOS system upgrade admin notes) did this:

       for zone in base pkgbuild ftp www src smtp
       do
         zlogin $zone shutdown -i5 -g0 -y
       done

    rather than this

       for zone in base pkgbuild ftp www src smtp
       do
         zoneadm -z $zone shutdown
       done

    Normally I would use 'zoneadm' to do the shutdown.  However, I am
    pretty sure that the former (based on 'zlogin') encountered the same
    problem.  If so, that is very interesting.

    In the shutdown loop, two of the zones encountered the problem.
