Since we re-use the file for a new segment, without overwriting the
old contents, it seems like we would need to do *something* to
reliably determine when we've hit the end of a segment and have
moved into old data from a previous use of the file.  Would your
proposed changes cover that adequately?  (I'm not sure I understood
your proposal well enough to be comfortable about that.)
