fork-and-beep test program

`man ioperm` currently states "Permissions are not inherited by the child
created by fork(2); following a fork(2) the child must turn on those
permissions that it needs." This is not true. I do not know if it was true at
some point in the past, but ioperm is preserved across a fork at least as far
back as Linux 2.6.26.

A test program to demonstrate this behavior is attached.
