All methods on this interface must be thread-safe. ÚtaskNÚreturncCódS)a; Perform the given task. As an interface, this method makes no specific claims about concurrent execution. An L{IWorker}'s C{do} implementation may defer execution for later on the same thread, immediately on a different thread, or some combination of the two. It is valid for a C{do} method to schedule C{task} in such a way that it may never be executed. It is important for some implementations to provide specific properties with respect to where C{task} is executed, of course, and client code may rely on a more specific implementation of C{do} than L{IWorker}. @param task: a task to call in a thread or other concurrent context. @type task: 0-argument callable @raise AlreadyQuit: if C{quit} has been called.
