[PATCH 2009-01-30] fix potential buffer overflow; fix wrong pid in msg; fix false positive PANIC

[Roland McGrath]

Also, these are really too many unrelated changes to be in one commit,
or in one ChangeLog paragraph.  Please separate things properly.

A couple of unrelated cosmetic things might go together.  But putting a
behavior change in the same commit with a buffer size fixup is never
acceptable.


Thanks,
Roland
