-----------------------------------------------------------------
Second failure is complicated only by the fact that at the time of failure
there is a second thread (thread-0) working on the record. This is likely
because of the failure itself. Otherwise, only one thread is involved in
modifying the record in question and looking at it, so it would seem to be an
open-and-shut case of database corruption. Only potential ManifoldCF
involvement would be if there was caching going on - which should not be
happening, but must be confirmed.
