In order to support tasks notifications and progress updates we need to establish a channel & proxy by which those events can be sent from the process executing and producing those events and the originating process that requested that task to be executed. This review adds on such a proxy and adjusts a cloned tasks notification callbacks to place messages on a queue that will be picked up by a thread in the originating process for dispatch to the original callbacks that were registered with the non-cloned task (therefore making the original callbacks appear to be called as they are supposed to be).
