A challenge (was Re: Of course, they'll deny it.)

[George Toft]

Yet another demonstration os how perl does everything better/faster

That line choked the box pretty quick:
hawaii:~ # w
  4:08am  up  1:55,  2 users,  load average: 244.33, 118.20, 46.24

Now all I have to do is get my box off HST and onto Arizona time.
