> The stuck threads were stuck in sun's SSL code. Geode's client/Server
> framework uses old I/O and that was also part of where they were stuck. If
> the clients had closed their connections to the server then it would not have
> been stuck here. But the server shutdown shouldn't hang because of client
> that refuses to disconnect.
