Instances from these new classes should run on whatever thread the root was created on. Child classes inherit the parent's safety.</p>

An instance of the class will execute functions only on the thread that made the object in the first place. The class is useful in a GUI's main loop.</p>

Revision 16. </p> <p>A simple, flexible, general-purpose observer pattern.</p> <p>Observers can be callable objects or objects with a particular named method (handle_notify() by default). Events can be any object, and observers can select which events they are interested in receiving. Support for a number of different types of lightweight event objects is included.</p>
