I don't see a problem with making this file world readable.  Doing so would be
in keeping with most of the other stats bearing files in /proc/<pid>.  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.
