Oh. Yeah. I, uhh...I knew that, I was just testing you. Ahem.
Thanks to Rob and Charles for point this out. I wonder what the
rationale for the restriction is, however; I suppose I'm thinking about
Unix dup too much when I think of cloning. Probably an artifact of
thinking of fid's as being more like file descriptors than they really
are. I guess the idea of duping can be adequately implemented by the
client and is unnecessary in the protocol. Since we're minimalists,
it would therefore be illogical to include it there.
