Mike, If it was in general unstable, we would be hearing a lot more noise on the list. I think you've just lucked into a couple bad/difficult geometry cases. Your buffer case sounds like the one here: http://trac.osgeo.org/geos/ticket/188 so hopefully it'll be patched up in the next release. Your disjoint case is new, perhaps you can find a pair of geometries that you know exercise it and attach them to an issue report?
