 * on an already-closed socket, and a socket caught mid-teardown may never run
 * the close callback at all. Both must settle, because callers await this on
 * the TURN failure path — a hang there would leave `#turnAllocating` pending
 * forever and wedge every later caller awaiting that same promise, and would
 * also block `Peer.stop()`.
