that is totally up to you and depends on the application. Usually, if you are 
watching for read+write events at the same time, you use the same callback on 
the same watcher, if you do write/read sequentially you will do that in 
different callbacks.

You mean to halt the watcher. Yes, you must do that.

You can. Why would you want to, though?
