Vortex.Ws.Door.Rate
Token buckets, one per peer and one for the whole door, and the count of open sessions. The arithmetic is pure (take1, opens); the gate keeps the rest in STM.

Refill for the time elapsed, then take a token if there is one.
Count a session in, unless the door or its peer is at the limit.
Count a session out; a peer with none left is forgotten.
Charge one frame to its peer and to the door. A peer's bucket that has refilled is forgotten, so the map holds only peers that are busy.
Count a session in, unless the door or its peer is at the limit.
