I came up with some very pretty code to fix this, which
tried to copy_to_user with a lock held.

After all my attempts to fix that fatal flaw resulted in much uglier
code I set it aside for a while in the hopes that inspiration would
strike.

and it's still sitting unfinished. :-(

But I want to finish it, honest! This latest discussion has
made me acutely conscious of it.

The fact that the scope of changes just got bigger doesn't help of
course, but I *have* picked it up again.
