Every manual nowdays marks rand() as deprecated. Yet it's still used bogusly for cryptographic needs - e.g. even XFree86 4.x seems to use rand() for generating cookies, I discovered last night (as a result of my rand() warning :-). If we fix up rand() to have a decent cryptographic behaviour, we save all the idiot programmers from themselves.
