Most of the Pirate patterns are synchronous, i.e. clients use REQ
sockets and send one request at a time. This means there is no upfront
sharing of work, unlike a PUSH/PULL model. These patterns are all
built on the LRU model, where workers only accept one request at a
time, and requests are only sent to workers that aren't busy. So you
can add / remove workers at any time, and requests are distributed
properly to available workers.
