# A very simple algorithm based on incremental balancing of job queues.
# Initially, the first queue has all the jobs that are gradually distributed
# across available queues. The algorithm doesn't take much memory since it
# does not involve the recursive traversing of the options tree and
# doesn't store lots of intermediate data.
