Enforces single-threaded, serialized, ordered execution of onNext(T), onCompleted(), and onError(java.lang.Throwable).

When multiple threads are emitting and/or notifying they will be serialized by:

• Allowing only one thread at a time to emit
• Adding notifications to a queue if another thread is already emitting
• Not holding any locks or blocking any threads while emitting
