When a length prefix is received which is greater than the protocol's
C{MAX_LENGTH} attribute, the C{lengthLimitExceeded} method is called
with the received length prefix.

When L{basic.LineReceiver} is paused, it doesn't deliver lines to
L{basic.LineReceiver.lineReceived} and delivers them immediately upon
being resumed.
L{ConsumingProtocol} is a L{LineReceiver} that pauses itself after
every line, and writes that line to its transport.
