There is probably room for improvement here under JDK 1.4, if we
want to get really fancy. I think we could manipulate IO buffers to read
directly from the network into byte arrays, rather than reading in from
the network at the hardware level, allocating a new buffer in the program,
and then copying the data from the network buffer to the program buffer.
But of course, IANAIOGuy; I've never actually tried that... :)
