interface ProtocolStateMachine<R>
A ProtocolStateMachine instance is a suspendable fiber that delegates all actual logic to a ProtocolLogic instance. For any given flow there is only one PSM, even if that protocol invokes subprotocols.
These classes are created by the StateMachineManager when a new protocol is started at the topmost level. If a protocol invokes a sub-protocol, then it will pass along the PSM to the child. The call method of the topmost logic element gets to return the value that the entire state machine resolves to.
