signal handlers not linked properly in do_fork()?

    I've been looking at the code for do_fork() / copy_sighand() and am
    mystified by the following. It seems that copy_sighand() only sets the
    new task's sig member if it is not CLONEd from the parent.

    If the signal_struct is CLONEd from the parent, it increments the parent's
    signal_struct's reference count, but does not set the new task's sig
    member. I see nowhere else in do_fork() where sig is set, either.
    What gives?
