The test is supposed to set an invalid Program Counter and check whether
the kernel does not crash. On strict architectures (notably SPARC) there
might be (and it was reported) a kernel panic.

Double wait is supposed to first wait for the child to exit cleanly,
then assert that it is already gone.

If the problem is still there, I plan to have a look over the weekend.
