That's not what the patch fixes. The patch attempts to make it so that if a "replayed hostsubnet delete" occurs, that we do the right thing. But we don't know how to actually cause the "replayed hostsubnet delete" (or even if that really is the right description of what's occurring), so the fix can't really be QA'ed at this point (other than to make sure that it doesn't break anything else).
The real test will be when we get this fix deployed to Online, and we see if the node-to-node routing problem goes away.
