Oh well, thanks for the useful link. That thread was illuminating.

I ended up switching to an iterator object, implementing "__iter__" and
"next" in a class that wraps around the process. This required a bit of
reworking since the algorithm changed from a push model (which I would
consider callbacks and generators to be) to a pull model.

Thanks, everyone, for the helpful responses.
