If you believe that the deadlock problems we address here can be
better fixed by making reclaim more intelligent then please post a
patch and we will test it. I am highly skeptical, but the proof is in
the patch.

It is already easy, and it is already fixed in this patch series.
Sure, we can pare these patches down a little more, but you are going
to have a really hard time coming up with something simpler that
actually works.
