I think the TLB shootdown should guarantee that it's ok on other
CPU's, since that's basically what we do on mmap.
But looking closer at this, I think I see why the old code did what it
did. I think it's breaking shared mmap pages on purpose rather than
dirtying them. Which is probably the right thing to do.
