Yup -- I checked that code and found out that nonInVacuumXmin can be
taken out as it's not used anywhere. One upside of this is that taking
it out means we can remove all diffs to GetSnapshotData. New patch
attached; it's a bit smaller than the last one.
I'm currently testing it. Since it appears there are no further
objections, I intend to commit it.
