After looking at O->A loaning code in yamt-pagecache branch, looking at
the benchmark results by Jaime (some data was sent privately, I think)
and contemplating about this mechanism - I tend to think that O->A loaning
should be removed. It is a significant code complexity in UVM with some
special casing and benchmarks indicate that the benefit is somewhat small.
Does not seem to be worth, does it?
