This stuff seems sensible enough that I think we should at least have
a test, no?  It does not have to be absolutely perfect in terms of
reproducibility, just good enough to be able to detect it across the
buildfarm.  We already do various things with page boundaries in WAL
during recovery, and a shutdown could be perhaps timed to increase the
reproducibility rate of the issues discussed?
