The idea behind this new scheduler is the following:
lbfactor is <i>how much we expect this worker to work</i>,

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)
