Make regression tests run over 3x faster. This was mainly a matter of reducing timeouts and delays, paying special attention to every test that took longer than a second to finish. We could do better here; IMO anything over .7 sec is probably too long, but it's a big win as it is. Remember, interactive computing is a big win over batch processing: anything that makes you get up and walk away from the terminal might as well be making you carry your punch cards over to the mainframe.
