I noticed that things speed up quite a bit if I move the mouse in
circles for 10 minutes.  The Linux kernel sure makes me work for my
random numbers. ;-)

I'm a bit wary of urandom since it will cut down on the search space for
my key.  If I need to wait a few days for my 28 keys to be crunched, I'd
rather just wait.
