I did some experimentation just now, and could not get mysql to accept a
command longer than about 1 million bytes.  It complains about 
	Got a packet bigger than 'max_allowed_packet' bytes
which seems a bit odd because max_allowed_packet is allegedly set to
16 million, but anyway I don't think people are going to be loading any
million-row tables using single INSERT commands in mysql either.
