My only question is what log importance level this should be. In @jeffkl's example where constructing the graph takes 30s, it'd be really nice to see it! But in a lot of smaller repos I'd rather avoid a log line like this.

@baronfel do you have opinions?

I kinda want a deferred message, where we log nothing unless it takes 5s (or something) and then log at high pri. But we don't have anything else that works like that and it sounds kinda annoying!
