Load balancing with REQ and REP

[dremekie]

Looking at #143 I see mention of built-in load-balancing with REQ

@reqshark mentions: REQ/REP was designed around the need to distribute precise load balancing tasks among stateless workers

Could you provide an example of this (perhaps in /examples)? Is a device actually needed?

Thanks much

the pattern w/ automatic load balancing is PUSH/PULL, see #118.

REQ/REP provides a full manual control mechanism for constraining backpressure, since REQ won't fire again until the next REP msg. Building out your load balancing topology with REQ/REP seems less builtin to me. Here's how I see it:

🏎 REQ/REP: 5 speed manual transmission with a heavy clutch

🚐 PUSH/PULL: luxury SUV with automatic
