Description
If the client connection is disconnected with zoo server, cancelledkeyexception will arise.
Here is a strange scenarios.
NIOServerCxn.doIO is blocked at line 333 by the fail-slow nic.
If the delay lasts more than 30s, cancelledkeyexception will disappear.
If the delay lasts for 25s, cancelledkeyexception will arise.
When the doIO encounters the slowdown caused by teh fail-slow nic, the context is same.
