Comment (by daira):

 It seems as though the `IN_EXCL_UNLINK` flag would help with this:
 {{{
    IN_EXCL_UNLINK (since Linux 2.6.36)
           By default, when watching events on the children of a
           directory, events are generated for children even after
           they have been unlinked from the directory.  This can
           result in large numbers of uninteresting events for some
           applications (e.g., if watching /tmp, in which many
           applications create temporary files whose names are
           immediately unlinked).  Specifying IN_EXCL_UNLINK changes
           the default behavior, so that events are not generated for
           children after they have been unlinked from the watched
           directory.
 }}}
