The TCP transport implementation in Twisted calls the protocol's dataReceived
method *immediately* with any bytes it receives.  In other words, received
data is never buffered.  So the answer to your question is that the number
is always zero.

Additionally, TCP has no notion of messages.  There's just a stream of bytes
from which arbitrarily short or long sequences of bytes may be read.
