          - override default_child_processes() and log a warning
        * Scripts/webkitpy/layout_tests/run_webkit_tests.py:
          - fix a typo that caused us to print a method object instead of the
            value the method object returns in the case where there is only
            one child process.
        * Scripts/webkitpy/layout_tests/run_webkit_tests_unittest.py:
          - Add unit tests for the output of run_webkit_tests - in this case,
            the handling of --child-processes and --print config
