It's a user pointer, and while the permissions of the file are pretty questionable (should it really be readable to everybody), hashing the pointer isn't going to be the solution. We should take a closer look at more of the /proc/<pid> file permissions in general. Sure, we do want many of them to often be readable (for 'ps' and friends), but I think we should probably do a few conversions from S_IRUGO to S_IRUSR.
