    Remove the -rand /dev/urandom piece. I tried your command both with and
    without this option, and without it, it ran in under a few seconds on my
    p3 700mhz. (You wouldn't want to use /dev/urandom anyway, as it is
    providing 'fake' entropy; which is fine for _many_ tasks, but server
    keys should probably use the real thing..)
