<hr />
<p>Process events objects, can be specialized via subclassing, thus its 
  behavior can be overriden:</p>
  <p>Note: you should not override __init__ in your subclass instead define
  a my_init() method, this method will be called automatically from the 
  constructor of this class with its optionals parameters.</p>
  <ol start="1">
    <li>
      Provide specialized individual methods, e.g. process_IN_DELETE for 
      processing a precise type of event (e.g. IN_DELETE in this case).
    </li>
    <li>
      Or/and provide methods for processing events by 'family', e.g. 
      process_IN_CLOSE method will process both IN_CLOSE_WRITE and 
      IN_CLOSE_NOWRITE events (if process_IN_CLOSE_WRITE and 
      process_IN_CLOSE_NOWRITE aren't defined though).
    </li>
    <li>
      Or/and override process_default for catching and processing all the 
      remaining types of events.
    </li>
  </ol>

  empty here and must be redefined to be useful. In effect, if you need to 
  specifically initialize your subclass' instance then you just have to 
  override this method in your subclass. Then all the keyworded arguments 
  passed to ProcessEvent.__init__() will be transmitted as parameters to 
  this method. Beware you MUST pass keyword arguments though.</p>

  <p>By default this method only reports warning messages, you can 
  overredide it by subclassing ProcessEvent and implement your own 
  process_IN_Q_OVERFLOW method. The actions you can take on receiving this 
  event is either to update the variable max_queued_events in order to 
  handle more simultaneous events or to modify your code in order to 
  accomplish a better filtering diminishing the number of raised events.
