Done.
Thanks Artem, Dmitry and Heikki.
I wonder how we might be more systematic about this. There are some
general principles that were not respected here, but I'm not sure if
they're even written down let alone defended with code. Something to
think about.
It's not great to add a new use of BufferGetBlockNumber() (in terms of
false sharing just to get a value that we must have had moment earlier
in order to pin the buffer), but we do that all the time. That seems
like a micro-optimisation worth looking into in some systematic way
across all AMs.
