title: Apache commons exec causing high CPU usage
body: <p>Calling a particular executable (Jadeo) via commons-exec (using pipes for it's I/O) is causing massive CPU usage (over 30x) compared to calling same executable from the terminal. Idle wakeups are huge.</p>
  
  <p>I've talked to the developer of the executable and they suggest that using blocking I/O may be causing these excessive wake ups.</p>
  
  <p>Is there a way to use non blocking I/O with Apache commons-exec instead?</p>
  
  <p>Or is there another library that uses non blocking I/O?</p>
