Ability to leave Selenium RC (and the selenium window) open and running at end of tests

It can be annoying that the RC shuts down at the end of a test run; when debugging tests it would be useful to leave it up to read logged messages or see the state of the app. Perhaps a command line option (-Dtapestry.stop-fixtures=false) that says leave Jetty and Selenium RC running even at the end of the test suite.
