monitor: Fix directory symlink deletion handling

Browse Source 
When a symlink to a direcotry is deleted inotify cannot tell it from a
regular file rendering all its children orphans.
This sometimes leads to an unexpected effect - they may appear later in
a newly created directory when it gets an id used by the deleted symlink.
