    Yes. Signals are represented, in the kernel and in the API, as bits
    in fixed-size bitmaps.

    POSIX real-time signals, if we implemented them, would at least give
    you the opportunity to queue signals, with unique ancillary data
    attached to each instance. We have all the mechanism to do this in
    the user-kernel interface; it's just not implemented in the kernel.
