    ok, got it (off-list) and you seem to have the default HZ=250. Could you
    change it to HZ=1000 - does the delay get alot smaller?

    if yes then this could be roughly the expected worst-case behavior for a
    nice+19 'signalling' task - i'd suggest to try the dont-use-renice patch
    Rusty sent (with the hang it causes fixed), or to change the nice(19) to
    nice(10).

    (the rq_clock behavior still looks a bit anomalous, that perhaps
    contributes to the problem.)
