Thanks for the patch! That sounds like a great addition. I was doing some
tests and did not see any issues. Also while doing the tests I thouhgt that it
could be useful to evict only from a subset of NUMA nodes (now that NUMA
awareness is in). We'd need to figure out what to do for buffers that are spread
across NUMA nodes though.
Does that sound like an idea worth to spend time on? (If so, I'd be happy to work
on it).
