Ayup!

I would differ, but that's irrelevant.

This is part of what I was getting at, in a roundabout way. If you use
a CRC, hash, or any other kind of non-trivial check code, you have a
certain level of confidence in the data, but not a guarantee. If you
decide, based on your expert opinions, that a 32 or 64 bit CRC or hash
gives you an adequate level of confidence in the event of a crash, then
I'll be satisfied, but don't call it a guarantee.

Them's small nits we're picking at, though.
