While I have not investigated the leak in any detail, it is useful to 
know that SVG rendering is based on MVG drawing commands and there is 
an unusual design in that the Image accumulates every MVG drawing 
command since the dawn of (its) time in a huge attribute string with 
the key "[MVG]".  Besides consuming ever more memory, you should 
notice that execution gets slower.

It is likely that adding the line

   image.attribute("[MVG]","");

to the loop will eliminate most of the leak by resetting the attribute 
to an empty string.
