This is a temporary fix to deal with websockets code using write_nonblock. The problem with implementing it properly is that it means we'd have to have the ability to rewind an engine because after we write+extract, the socket write_nonblock
call might raise an exception and later code would pass the same data in, but the engine would think it had already written the data in. So for the time being (and since write blocking is quite rare), go ahead and actually block in write_nonblock.
