    Hmm.. For me, Dan's program (with "-DBUG -DNOTHREAD") results in a
    sleeping parent, and both children are likewise just sleeping. Despite the
    fact that the parent just did the PTRACE_KILL on child2.

    I didn't trace it through the kernel, it just looked like PTRACE_KILL
    didn't do anything.
