Comment (by simonmar):

 I don't see a bug here.  The test succeeds, although it needs an extra
 `sleep 1` for systems with low resolution file timestamps (that is very
 likely the case in Simon PJ's failure linked above).

 @heisenbug: please could you try again to reproduce it and update the
 instructions if necessary?  In the meantime let's add the `sleep 1` and
 then close the ticket.
