Internal struct for receiving results from multiple subtasks in parallel

Fields

ret_counter	Atomic counter counting missing arguments before this join can be executed.
joinfun	Function to execute when all arguments have arrived.
joinarg	Extra argument to pass to joinfun only used when joinfun is ReduceStyle::Arg.
