See the Cookbook recipies 8.7 and 4.17.

Writing correct shuffling programs is tricky. Looks like yours might have key collision issue. I've learned to trust the cookbook when I'm not sure.

p.s. Are the above links legitimate? I've never been there before (since I have my dogeared cookbook right here.) Does O'Reilly really condone the CD bookshelf being put on a public webserver like this?

Update: Guess I got my question answered... Removed links to recipies. (There actually are books out there that encourage this type of usage. In fact, at least one of them is published by O'Reilly, if I'm not mistaken.) I stumbled on to the bookshelf site when I went looking for the code ftp site. Didn't know if it was legit or not. Sorry.
