RT aren't really to blame: random number generation
is an arcane art that a lot of books and courses
tend to cover badly. Very few people realise that the
algorithm suggested by ANSI is flawed simply because
it's the standard - it must be safe. They implemnt
it or a variation of it because it's easily available,
widely used and seldom criticised outside scientific

I wouldn't say I'm an expert, but I have quite a lot
of experience in writing them. If you want a good
introduction, Numerical Recipies in C has a good
chapter on random number generation. I will probably
implement a subtractive method generator tonight
and post the code to the list anyway...
