title: What does the remote-actor framework do if trying to write to a client which is no longer there?
body: <p>I have a server which is using the remote actors framework to communicate with multiple clients. As mentioned in <a href="https://stackoverflow.com/questions/1058450/how-can-i-identify-a-remote-actor">this question</a>, I am having trouble keeping track of when a client disappears. Hence my server is still attempting to send messages to non-existent clients.</p>
  
  <ul>
  <li>Is this a problem? (<em>I don't see any exceptions being thrown</em> - but I assume there'll be memory issues if my server is long-lived)</li>
  <li>How can I detect that a message is being sent to a client no longer listening? (<em>If I want to implement some kind of connection clean-up</em>)</li>
  </ul>
