Imagine this for a second. You work on fixing something, get the required reviews, and run your patch on the try server. Everything looks good. Then you set a flag or something on the bug, and go home, and enjoy your evening. The next morning, you're reading your bugmail while enjoying your coffee, and you see a message from landingbot@mozilla.org saying that the patch has successfully landed on mozilla-central, you smile, and wonder how people used to spend 4 hours watching the tree (and possibly getting yelled at by me or philor in the meantime) when they wanted to land something on mozilla-central. This, my friend, is what we need to move towards, I think.
