    This is exactly what I needed, thanks. However, it appears to not have
    solved all of my problems.

    After I make this call:

    | shadow_task = copy_process(CLONE_FS | CLONE_FILES | CLONE_PARENT,
    | current_task->thread.esp, tmp,
    | 0, NULL, NULL);
                    
         (tmp is my new struct pt_regs*)
            
    And then this:

    | wake_up_forked_process(shadow_task);

    I see that the new process (shadow_task) gets scheduled once (I put some
    printk's in the scheduler), but never again. It dies quietly, and
    disappears from the process list. In addition, after the syscall, each
    process should make a call to printf() with their PID, but only the
    original process actually does it.

    Can you see anything else that I'm doing wrong? Any help would be
    appreciated.
