Anecdotally, leaving open for long periods of time causes problems, when that tab tab that includes Flash. Since Flash is fairly prevalent among Web ads, etc., it basically happens all the time. I'm sure there's some configuration setting or extension I could use to change this behavior. However, switching to Safari fixes it as well (and gets me improved battery life overall). I haven't really noticed any downsides to using Safari vs. Chrome.
