Proposed vos and vldb_check changes are in gerrit 2235 and 2236. It
makes 'vos' output look like this; how's this?

    RWrite: 537350927 
    number of sites -> 1
       server lenny-1 partition /vicepa RW Site 
    Volume is currently LOCKED  
    Volume is locked for a delete/misc operation

With similar messages for the other lock types. I was about to put the
information on the same line as the LOCKED message... but I thought it
might be bad for output-scrapers. And it's technically possible for more
than one lock flag to be set at the same time (though nothing does that

The lock timestamp is not available to 'vos', so we either need to get
new VL RPCs (I don't think it's worth it for this alone, but when they
are changed in the future, it's something to remember). Whether or not
to document the vldb_check route of determining this I leave to the
documentation people; it seems like a rather unsupported way of doing
things, but I don't know, still possibly useful.
