Threaded::synchronized() allows you to safely set or read synchronization conditions and act upon them (using ::wait() and ::notify()) knowing that only one call to synchronized() on the referenced object can be executed at a particular time, other calls from different thread contexts will block until the path is cleared by a call to ::wait() inside your ::Synchronized() closure.
