title: How long can a Worker Role process set status to "busy" before getting killed?
body: <p>I have a worker role process that want to stop processing new requests when it's too busy (e.g. CPU load > 80%, long disk queue, or some other metrics).</p>
  
  <p>If I set the role status to "busy", will it get killed by Fabric Controller after busying for too long time? If yes, how long will it takes until the Fabric Controller kill the process?</p>
  
  <p>I assume the process is still capable to receive/send signals to the Fabric agent.</p>
  
  <p>Thanks!</p>
