The RabbitMQ server and Java, Erlang and .net clients pass all the AMQP 
frames associated with content-bearing methods - i.e. the method, header 
and body frames - to the network layer before flushing the socket, so 
all these AMQP frames should generally only get split over multiple 
ethernet frames when exceeding the MTU size.
