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
.IR /tmp ,
in which many applications create temporary files whose
names are immediately unlinked).
Specifying
.B IN_EXCL_UNLINK
changes the default behavior,
so that events are not generated for children after
they have been unlinked from the watched directory.
