a additional patch to linux/Documentation/{core|dump}.txt (e.g.)
or Documentation/sysctl/kernel.txt sure would be nice. :)

Here's an addition to Documentation/sysctl/kernel.txt for
core_uses_pid and core_pattern plus a few other corrections.
Comments on it?
otherwise: Alan, Rik, Andrew, Dave, anybody? Please apply to 2.5.45.
Thanks,
