Description Kyle B CLA 2013-10-15 17:29:42 EDT 
Using CDO R20130613-1157, if a client is forced to shutdown (kill -9) the TCPSelector.run will enter an endless loop utilizing 100% of the CPU.

This bug occurs with my application, but able to reproduce using org.eclipse.emf.cdo.examples.master and org.eclipse.emf.cdo.examples.client.

1. Run ExampleMasterServer
2. Run ExampleClient
3. Open a new CDO session
4. Execute kill -9 <pid of ExampleClient>
5. View CPU usage. (top, system-monitor, etc..)
