Why does the left column here count upward 20 at a time?  Also, I did
od /dev/urandom > asdf and then hit ctrl-c as quick as I could, and
there were already 15,941 lines in it.  How random is this, really? 
That's a lot of "random" data being generated really quickly, is it
safe to use this for password generation a la diceware?
