    That makes sense.

    Sorry, SCHED_BATCH is unique to my tree at the moment so this is my
    mistake for not considering it. I'll have to transiently schedule
    SCHED_BATCH tasks as SCHED_NORMAL if we are going into swsusp. It's
    something I'll have to work on. In the interim, a workaround would be to
    convert all httpd threads to SCHED_NORMAL before shutting down in your
    scripts somewhere and convert them back after resuming.


    P.S. Raj the --cutme-- thing in your email is very annoying for those of
    us who reply to up to 300 emails a day (and yes I do know why you do it,
    but if you keep doing it people will stop replying directly to you).
