I do not quite understand what you want to do.  However, when a while loop
inside a function contains a yield statement, then cycling is controlled by
calling .next on the resulting gen-iterator.  This can be done from
multiple places, by any function with a reference to the iterator.  Hope
this at least gives you more ideas.
