While this is a noble goal, your method isn't really right: in TCP, the
chunks you write on one end do not correspond to the chunks you receive on
the other end after they've gone through a TCP stack and network. The best
way to verify that your client is stream clean is to write unit tests that
explicitly call its dataReceived method with different-sized chunks.
