It's spec complexity he was talking about--but anyway, making a hash
table or tree from a list doesn't seem complicated; maybe there are
other issues.  I suppose this could also be done with a per-object
flag, eg. arrayBuffer.setCloneTransfer(true), but as it's the
postMessage call being modified I'm not sure flagging it on the object
itself is clearer.
