But what portion of that is actually CRC-related?  XLogInsert does quite
a lot.

Anyway, I can't see degrading the reliability of the system for a gain
in the range of a few percent, which is the most that we'd be likely
to get here ... for a factor of two or more, maybe people would be
willing to take a risk.
