You have to remember that facebook is a compiled binary (hiphop). They entered the release cycle they did vs true Continuous Integration because original compilation times for this binary were extreme. Pretty sure Chuck mentioned something in the range of 1gb binary. They've corrected the amount of time it takes to compile and can push within 15 minutes of a trunk merge, but it's stil not on the scale of a few lines here, a few lines there.
