public abstract class AbstractRunnableModule
extends AbstractModule
implements java.lang.Runnable

An AbstractRunnableModule has its own running thread. This thread will call the abstract pulse() method periodically. The interval between two calls is determined by the sleepTime given to the constructor. Note: it is not guaranteed that the pulse() will be called on time. Scheduling algorithms determine the exact time when the pulse() will be called. Warning: only if the call to pulse() returns can this module call it periodically. Hint: providing a sleepTime of 0 will cause the pulse() method to be called _only once_. This is usefull if you want to control the thread yourself.
