Examples of kilim.Scheduler

kilim.Scheduler
This is a basic FIFO Executor. It maintains a list of runnable tasks and hands them out to WorkerThreads. Note that we don't maintain a list of all tasks, but we will at some point when we introduce monitoring/watchdog services. Paused tasks are not GC'd because their PauseReasons ought to be registered with some other live object.

     * The task contains an endpoint object, the bridge between the NIO system 
     * and Kilim's scheduling.
