    # One subtle behavior of p4 login -p, is that it will reuse any token
    # lying in a p4ticket file. What this means, is that if you sign on, say,
    # using the p4 command line, this method will end up reusing and returning
    # that ticket.
    #
    # So, make sure you run your web services instance in a clean environment
    # that you don't do interactive work (like maintenance stuff) under.
