Hummm… sounds like I need to look to create a pull request to get to
dinotify 0.2.3 or even 0.3.0.

I do want to avoid such low-level things, they may be required for
building libraries, but they seem totally the wrong level of concept
for an application.

I am definitely headed to the (select|poll|epoll) on the inotify file
descriptor to get the timeout, and then either read or check the input
channel for termination or an atomic Boolean state variable. Channels
seem most likely since parent threads send a terminating token.
