I have no stake in the ground for this either. My assigned task was to
minimize the effect of bumping up the possible cpu count to a really
large amount. This seemed to me to fall in this category. A side goal
was to prepare for even larger cpu count systems.

An alternative that Paul had suggested was to introduce a new set of
file interfaces that produce the alternate format. This would not
break existing interfaces and allow a transition, though how many
post-processors of the information would change is unclear. Given
that fact, would the added code and complexity be worthwhile?
