Watch for
Commands from different clients executing strictly one at a time on the single thread — never two at once.
More about this scenario
You'll learn
How one thread serves many clients by never blocking — accept, then run each ready command to completion in turn.
How it runs
CONNECT puts a client in the accept backlog. Each TICK is one turn of the loop: it accepts pending connections and runs the ready command callbacks, one after another, against the shared in-memory store.
