After communicating with the controller you
should follow their instructions and advise them of any
deviation.from
those instructions. As they have the responsibility for maintaining
separation, they have to know where everyone is and what everyone is
doing.

In the U.S., the class D tower controller is not responsible for
separation in the class D airspace. Only on the runways. That should
give a U.S. pilot more leeway in a situation as described in the
original post. Since the tower controller is not responsible for
maintaining separation between aircraft, I'm more inclined to take
action on my own to ensure that separation is maintained. The caveat
being that I will inform the tower of what I'm doing and why.
