Or why not return an error, as soon as possible on the socket, eg 
ENOBUFS, and discard anything in the queue before that. Make it 
configurable via a sockopt if you think it'd harm ordinary apps 
(though, anything that cant deal with ENOBUFS is broken already, 
really..) or make it apply only to nonblock sockets.

That seems more complex than needs be, for userspace at least.
