The have_ring stuff should probably be removed all across the singular interface. It was a means to speed up stuff like diff() by not having to set the Singular ring over and over again. However, since we use libSingular (or should be using it) this ad-hoc-ish improvement is no longer needed and should be removed. So: Don't worry about it and I'll provide a patch to remove it everywhere else soon.
