Don't block when flushing a full protocol buffer

Browse source 
In case the client isn't responding, this will block the compositor.
Instead we flush with MSG_DONTWAIT, which lets us fill up the kernel buffer
as much as we can (after not returning EPOLLOUT anymore it still can take
80k more), and then disconnect the client if we get EAGAIN.
