That was my first reaction as well:

However, from the discussion it seems like it will be harder to do it
that way (during normal operation, a checkpoint is what syncs the files;
but as Tom points out, bootstrap mode does not). Also, I would expect
the fsyncs to be in a less-controlled pattern, so it might perform more
poorly.
