I verified the data.

In this case, it was lost transactions, not data corruption. Should be
more careful. I had copy/pasted the "no data corruption", should specify
what was lost.

A couple of the latest transactions were gone, but the database came up
in a consistent state, if a bit old.

Since Linux wasn't the stuff I actually was testing, I didn't run very
many tests on it though.
