Doing so would be in keeping with most of the other stats bearing files in /proc/. The only reason I didn't make it world readable was because the getrlimit sematics previously kept limit information private to the process, and I didn't want to deviate from that. But as long as we're not making it world writeable I think we're ok. Acked-by: Neil Horman
