Basically, I absolutely hate the notion of us doing something
unsynchronized, when I can see us undoing a mmap that another thread
is doing. It's wrong.

You also didn't react to all the *other* things that were wrong in
that patch-set. The games you play with !fatal_signal_pending() etc
are just crazy.

End result: I absolutely detest the whole thing. I told you what I
consider an acceptable solution instead, that is much simpler and
doesn't have any of the problems of your patchset.
