* event loop of the Reactor and the Followers wait on the
* condition variable.
*
* This implementation is to work with the Muxed Transport
* Mechanism. Here the state variables such as <Condition
* Variable> etc cannot be kept in the Wait Strategy, since the
* Wait Strategy is per Transport object and here the Transport
* is Muxed and hence there are multiple threads running in the
* same Transport context.
