There, it was shown three times, when it should have only been shown twice. (For 2 expected failures out of 4 tests)

The reason is because sb_config._fail_page wasn't getting reset between tests.

Also note that -v, (verbose mode) will also trigger the --list-fail-page option, (if not running multithreaded tests).

Another issue with --list-fail-page is that sometimes the output doesn't appear until after all tests have completed. (A fail page URL should be displayed after each failing test.)
