@erikj79 I don't really see a significant difference in the build time of `images` on my machine when comparing before and after the patch (but, as Magnus says, the build times tend to fluctuate, so it's hard to get an accurate assessment. Maybe the difference is a couple of minutes. Not that big a deal for a 30-ish minute build).
