    We have a lwp_kill() system call that sends a signal to a thread within
    a process.  It turns out to be fairly necessary for any sort of heavily
    integrated multi-threaded work.  In our case we need it to be able to
    issue IPIs (aka SIGUSR1) to cpus within a SMP virtual kernel.

    int lwp_kill(pid_t pid, lwpid_t tid, int sig);
