Okay, I got this working, kinda, after mucking around a bit. What I
want is a daemon-like thingie which will give me notifications when
stuff inside a partocular directory changes. Is it advisable to wrap
the cn.wait call inside an infinite loop, for this? Are there any
consequences for that?
I did something like this:

while true
	cn.wait{ |s|
		puts "Something changed"
		puts "File: " + s.file_name
		puts "Action: " + s.action
		}
end

This does detect file changes, but I donot understand how I get away
without calling cn.reset. Is that invoked when the block is called?

Thanks!
