It would be cool if it were easier to figure out how to re-run a single test.

In #14111 (closed), I had a set of tests fail. Re-running them one at a time wasn't too easy. At first, I thought that the --test option to run_tests.py would help, but it turned out to do something different.

It would be cool if, after seeing a string like ERROR: test_pid_by_name_ps_bsd or test_pid_by_name_ps_bsd [FAILURE], I could just pass test_pid_by_name_ps_bsd directly back into the run_tests.py script and repeat the single failing test.
