Hello hackers,

What exactly is a savepointLevel?

They seem to have been there for 15 years[1], diligently copied from
parent transactions to children, fastidiously checked to avoid crossing
a level on rollback or release, but does anything ever change the level
from its initial value? I'm drawing a blank[2].

Regards,
-Chap
