        lbstatus is <i>how urgent this worker has to work to fulfill its quota
        of work</i>. We distribute each worker's work quota to the worker, and then look
        which of them needs to work most urgently (biggest lbstatus).  This
        worker is then selected for work, and its lbstatus reduced by the
        total work quota we distributed to all workers.  Thus the sum of all
        lbstatus does not change.(*)
        If some workers are disabled, the others will
        still be scheduled correctly. (mturk)
