Linus has always advocated doing the right thing even when it breaks
applications (piles of examples out there). We can not keep carrying
cruft in the kernel forever.

In this specific case, the random PIDs will help make it harder to
exploit a bunch of attacks on predictable filenames (all of our
userland should be using mkstemp instead of mktemp eventually, just
like OpenBSD).
