well, apparently, you're not doing it "at once". if you do everything
within a single iteration of event handling (i.e. before the canvas
idle handler is invoked), there is only *one* canvas redraw.

otoh, my experience so far is with gtk1.2, and its possible that
something horrible has changed in gtk2 (i'll be discovering that in
april or so :) however, i believe that this aspect of the canvas is
similar in gtk2 as in gtk1.
