Except it is a lot more efficient and easy to do "dd if=/dev/urandom bs=1k ..." than to spin in a loop getting 16-bit random numbers from bash. We would also be at the mercy of the shell being identical on the user and debugger's systems. I don't think that running this test once in a blue moon on some system is going to be a source of problems.
