So having a system that cannot be safely shut down because someone has opened a file handle on a remote fs that became unavailable is preferable to special-casing one signal?

Let's add two new system calls, something like "terminate with extreme prejudice" (abbr. twep) and "unmount without mercy" (abbr. uwm).
