  Or to quit forking out for ever-increasing bus fares and get a motorcycle.

  Sorry to be off-topic, but that looks like the sort of operation where
genuine parallel processing would be useful. E.g. about 20 years ago I heard
of a computer called the `Connection Machine', which acted somewhat like
0x10000 Commodore Pets serial-numbered from 0 to 0xffff all sharing one
control unit; each was linked to the 16 others whose serial numbers had one
bit different. So it could do the same thing to up to 0x10000 elements of an
array at once. When will something like that be available in PC's?
