    volmonitor keep vtrans lock
    
    VolMonitor must maintain the VTRANS lock the whole time it is walking
    the allTrans list.  Failure to do so can cause core dumps trying to
    access memory that has already been free'd.
    
    Two versions of this change were coded and tested.  The other version
    used the VTRANS lock only around a THOLD, but needed a TRELE, too.
    Timing tests were run counting the number of vos status, vos listvol,
    and vos backupsys operations that could be performed during a fixed
    number of vos status operations.  The THOLD/TRELE version caused other
    vos operations to run about 5% slower.
