Well, premature optimisation and all that.  I think I can see how to refactor it to take those possibilities into account, but I’d like to know whether it basically works as-is before I try that.

On the assumption that most people who are more interested in the overhead code have already grabbed it, I’ve pushed it to the sch_cake repo so that we’re on the same page.
