Hi, After talking Alex and Carol, we've come up with a convention for excluding tests that need time for repairs or that are questionable. I've documented this on the Mustella wiki [1]. Basically, the ExcludeList[Mac|Win].txt file should be used only for tests that do not run on one operating system or the other. When you come across a test that is giving you trouble, comment it out and include in the comment the string, FIXME, along with a short note. Later we'll search for "FIXME" and begin addressing those test cases.
