I don't think there is a clear picture yet of what benchmark to use for
testing changes here. Items like "Consider adding buffers the
background writer finds reusable to the free list" have been on the TODO
list since 2007; neither ideas nor code are the problem here. Proving
that a) a new policy helps on some workloads and b) it doesn't harm any
important workload, those are the hard parts here.
