--- Comment #1 from Brad Roberts <braddr at puremagic.com> ---
Needs more explanation because it does.  The auto-tester knows about new pulls
and updates to pulls as soon as they occur, modulo delays w/in github's
notification delivery infrastructure.

At least the one labeled 'auto-tester' in the github status.
