First, we need to be sure this code can be freely distributed under
DJ's license.  Sometimes universities are picky about this and might
require some blurb like what BSD did--which will return us back to
square one.

And second, one of the most valuable features of `random' is that all
its bits, inluding the LSB's, are random, so you could get a random
bit with "random() % 2".  Does your algorithm have this feature?
