Thanks for forwarding that. I've bounced your mails to a few extra
folks, please include them in CC in future. Neil last touched the
coredump pipe stuff before me, Jakub reported the spaces in
core_pattern issue and Andrew merged my patch.

The patch seems like a reasonable approach but I don't have much
experience with Linux kernel internals.
