[Mono-dev] Can a TCP Socket SendAsync operation complete without transferring all the bytes in a BufferList?

I asked this question on Stack Overflow in regards to the specification. 
In Mono 3.12 (under Red Hat 6), a call to SendAsync with a SocketEventAsyncArgs that was using a BufferList completed with SocketError.Success but an incomplete BytesTransferred. Is this behaviour acceptable under the .Net specification? 
Windows' implementation seems to guarantee that all bytes are sent before the Completed event is raised on the SocketEventAsyncArgs.
So which (both?) is correct?
