> When you say the message is buffered redundantly, what do you mean? 

I mean, SOCK_STREAM sockets are buffered. The socket API doesn't say when and what amount of data is sent.

I also mean:
Kernel does not guarantee anything regrading the message sizes.

In other words:
With stream socket, possible non-message-border-aligned data has to survive across your read buffer. Thus you need to buffer fractional messages in your application code.

Quickly glancing to the diff I would say your patch doesn't take this into account, but again, sorry if I'm wrong.
