     In my opinion it is the same. If you use python-inotify, you invoke 
the inotify system-call programatically (through a function call or an 
object); otherwise you rely on another process to do it and pipe you the 
events. The last solution is fine for designing and testing the thing 
but not really for a production daemon.
