The one on Plan 9 ISO image is exactly 73,464 bytes, like yours. Strange
thing, because MS-DOS COM executables are exact memory dumps (no
loader/header/relocation) designed for 16 bit systems which had a
"segmented" memory model (segmented in the ancient sense of the word).
They must fit into one 16-bit segment; exactly 64K.
