Yeah, I thought they would.  If you look at the first loop of
prepare_to_write_split_index() classifying which cache entries should
be included in the new split index, you'll see only two code paths
that could leave out an entry from the split index, i.e. where an
entry could be left with a non-zero 'ce->index' and without its
CE_UPDATE_IN_BASE flag set.  Now, with the fix in patch 5/5 both of
those code paths have the is_race_timestamp() check.
