tail -f in python with no time.sleep

Question

I need to emulate \"tail -f\" in python, but I don\'t want to use time.sleep in the reading loop. I want something more elegant like some kind of blocking read, or select.se

If you can use GLib on all platforms, you should use glib.io_add_watch; then you can use a normal GLib mainloop and process events as they happen, without any polling behavior.
