This PR does:

ensure that Weave compiles without Backoff after Weave as a background service #136
A parent will give half its tasks when waking up its children, whatever they requested.
This solves load balancing on backed off child wake-up. #90 by diffusing tasks much faster to the leaves.
Impact is 10% overhead reduction on fibonacci:
(~350 ms instead of ~385 ms)
This should significantly help when Weave is used as a background service as well.
