So I didn't really have any plans. I think it's a good patch, and it
might even fix a bug and improve code generation, but it didn't fix
the lockup problem, so..

If you think it's worth committing, then go ahead. Add my signed-off,
although I have to note that I didn't do a lot of testing of that
patch (I think it was compile-tested when I sent it out, and then I
ended up running it for a while, and obviously it got *some* testing
by the person who saw the lockup that just showed that it didn't fix
the problem ;(
