Subject: Tweaking the Task class a bit. -) setPreemptible now returns the
previous state -) Events may now not have an owner -) Events may now have a
callback (even though it still needs an owner to get into the ev_loop, for
these kind of watchers...)
TODO:
-) think about a way to start a watcher without requireing a Task
-) add a few more things in the Tasks unit tests
