    This may be an option, but I think we should be able to attach protocol
    decoders in parallel, directly to the IRQ handler. At least with RC-5
    (that's what I personally use) it means reliable decoding, no need for
    any timeouts, the code is clean, fast (can be a part of hard IRQ
    handler) and simple.

    The decoder needs something like
    rc5_signal_change(ptr, space_or_mark, microseconds).

    At least mark->space or space->mark events must be reported. For better
    reliability, both of them.
