See inotify(7) and inotify_add_watch(2) for further information.  The
inotify fd is managed internally and there is no corresponding
inotify_init.  Use `inotify-rm-watch' to remove a watch.

Also note, that the following inotify bit-masks can not be used, due
to the fact that descriptors are shared across different callers.
