That's great news, as it removes one of my greatest fears from reading
this thread - namely that there is a submarine patent on their
algorithms waiting to surface.

One of GPL's requirements is free grant of patent use.

But it may be that the free patent grant applies only to GPL code, so we
may be back to the problems we are struggling in ARC vs. LRU ;(
