> ioSession.close().join() with SO_LINGERING set behaves completely differently on Windows
and Linux.
> On a linux machine (acting as the server) when a disconnection occurs (say you pull the
plug on the client machine) and depending on the value set for the SO_LINGERING the whole
server will block for as long as the value specified in the SO_LINGERING.
> As far as I can tell it gets stuck in the lock.wait() of the IoFuture because it's not
ready.

>      * Wait for the asynchronous operation to end.
