Something we do fairly often is to copy the current .fs file from our
live web server for use on a development machine.  We don't bother to
copy the .index file at the same time, mainly because just copying the
.fs file is never enough -- it's usually done prior to running a
database update script that rearranges stuff to match our current code,
possibly followed by a pack.  So on the next database open, the .index
file is out-of-date with respect to the .fs file.  I was just wondering
how ZODB handles that case.  Guess I'll do some experimentation to find
out.
