 * IOEventDispatch interface is used by I/O reactors to notify clients of I/O

 * executed on a dispatch thread of the I/O reactor. Therefore, it is important 
 * that processing that takes place in the event methods will not block the 
 * dispatch thread for too long, as the I/O reactor will be unable to react to 
 * other events.
