> Disabling thrift results in unclosed thrift sockets being left around.
> Steps to reproduce and observe:
> 1. Have a handful of clients connect via thrift.
> 2. Disable thrift.
> 3. Enable thrift, have the clients reconnect.
> 4. Observe netstat or lsof, and you'll find a lot of thrift sockets in 
> CLOSE_WAIT state, and they'll never go away.
>   * Also verifiable from 
> org.apache.cassandra.metrics:type=Client,name=connectedThriftClients MBean.
> What's extra fun about this is the leaked sockets still count towards your 
> maximum RPC thread count. As a result, toggling thrift enough times will 
> result in an rpc_max_threads number of CLOSED_WAIT sockets, with no new 
> clients able to connect.
> This was reproduced with HSHA. I haven't tried it in sync yet.
