Created attachment 651921 [details] [diff] [review] patch Bug 719114 comment 35 has more discussion of this. I'm uncertain whether this would reduce crash volume. However, I think the risk of the doing extra compartment GCs probably outweighs the rewards, which I think are mostly for people with many tabs open.
