if you have a read/write DB, then the changes you make to the DB are
also visible, right?  it's not a static snapshot in that sense.

I think you're asking about a situation where you have a read-only DB,
and someone else has modified the database in the meantime.  Is that
correct?

In that case, it might also be nice to be able to detect *when* some
other change has been made, so that you can perform such a reopen.

I don't know xapian well enough to know whether that kind if
inter-process signalling is possible, though.  Maybe Olly can provide
some guidance here?
