Another exception for you:
In place messaging with a "fast message" format would be nice for
support. Some network hardware, including TCP via TOE cards and
infiniband and the like, support very low latency messaging, e.g. < 10
microseconds. You don't want to copy, but also you don't want to
serialize. In fact, for many applications you are prepared to sacrifice
architecture portability on the altar of speed and you might send a
contiguous c++ object, padding from alignment and all, directly as a
message block. The CPU never has to see the whole object.
