With ZopeHTTPServer I set SCRIPT_NAME to "" and the leading slash wound up in PATH_INFO. This was, as I recall, what Jim Fulton said it should be. I just discovered that ZServer seems to lose the leading slash from PATH_INFO. I've worked around the problem by setting SCRIPT_NAME to "/". Is this a bug or expected behavior?
