title: Can Akka actor drop messages from it's mailbox if needed?
body: <p>For example, if I want to remove redundant messages from the queue - so that when actor recieves <code>Connect</code> message, it should inspect it's mailbox and remove other <code>Connect</code> messages, in order to do only one connect instead of several.</p>
  
  <p>Is something like this possible?</p>
