Looks fine to commit, though please consider not using a new
"active_p" member variable in order to send edges on the active
pin.  This can be done by replacing ...

> + 	  if (UNLIKELY(! this->active_p))
> + 	    {
> + 	      this->active_pin.drive (1);
> + 	      this->active_p = true;
> + 	    }
> + 

with
	  if (this->active_pin.sense() != 1)
	    this->active_pin->drive(1);

and a corresponding change for the 0 transition.
