To optimize your calls to the parse() method, you _could_ use the Connection::expected()
and Connection::maxFrame() methods. The expected() method returns the number of bytes
that the library prefers to receive next. It is pointless to call the parse() method
with a smaller buffer, and it is best to call the method with a buffer of exactly this
size. The maxFrame() returns the max frame size for AMQP messages. If you read your
messages into a reusable buffer, you could allocate this buffer up to this size, so that
you never will have to reallocate.
