    These are general purpose pools of DUTs that are considered
    identical for purposes of testing.  That is, a device in one of
    these pools can be shifted to another pool at will for purposes
    of supplying test demand.

    Devices in these pools are not allowed to have special-purpose
    attachments, or to be part of in any kind of custom fixture.
    Devices in these pools are also required to reside in areas
    managed by the Platforms team (i.e. at the time of this writing,
    only in "Atlantis" or "Destiny").

        to guarantee timely completion of tests from builders.
    SPARE_POOL - A low priority pool that is allowed to provide
        spares to replace broken devices in the critical pools.

        monitored for health.
