I can elaborate further on the wiki tomorrow. The term in-flight in my
edit is a bit incomplete. It refers to what's "in-flight" on the
broker-side for actual handling - that is what provides the ordering
guarantee. The client can continue to write requests to the socket
even while the broker is handling a preceding request since those
requests will sit in the socket buffer. So there is still significant
benefit in using non-blocking IO/request pipelining on the client-side
to achieve high throughput.
