I think I am going to go the (select|poll|epoll) on the file descriptor
with a timeout and then the read if that is appropriate or check the
input channel for the terminate token if that is appropriate.

The question whether to do this in my code or create a "read with
timeout" in dinotify

Dinotify adds the tree monitoring as an extra over the inotify API but
U do not see any timeout related things.
