My opinion is that 3 or 4 GB is not a very small amount of RAM for a
personal computer.

I think that allowing users with "only" 4 GB RAM to build our ledger
package is worth it taking twice as long for the rest of us.

Or, users with ≤ 4 GB RAM could make a private variant of ledger that
disables parallel building. We sometimes suggest that users with
esoteric requirements or restrictions do something like this, but I
don't think this is one of those cases.

Thoughts?
