Interesting, but I tried them out in my Ubuntu 13.10 desktop and applying the whole lot completely killed Chrome. Strangely, certain tabs would consistently load fine, while others would end up with white screens - seemingly consistently per-uri over several browser launches and reboot. Other thing seemed to be working fine. Oddly, the settings screen was one uri that did not work. I took his file handle limits and scrapped the rest and it went back to normal. Something in there did not agree with my video card settings is my best bet.
