    Hello.

    The functions await() and asleep() in kern_synch.c
    are marked as EXPERIMENTAL/UNTESTED.
    Is this comment still valid? Does anyone have used
    those functions successfully? Should I better not
    use them in my device driver code for RELENG_4?
    How do I correctly cancel a request (as I should do
    according to the man page): "asleep (NULL, 0, NULL, 0)"?

    Any help appreciated.

    Norbert
