// REAL maxSockets accounting through an Agent: with maxSockets 1 the
// second request queues (agent.requests[name] holds it) until the first
// exchange finishes, and the counters read exactly Node's at every
// causally-pinned point — sockets[name].length at response time, the
// queue length, and the drained tables afterwards. Socket REUSE is not
// pinned (this client dials one connection per request — the documented
// divergence); only the counters and the strict first-then-second
// ordering are.
