That was a black out.  I don't actually think we should do that.  We should
rather implement it.  Sorry for the confusion.

The one you send me seemed to only on the schedule and timer
interface.  We have both, probably it didn't work to paste it into the
header file, but you need to put it into a seperate file and include the
correct glue headers.

Here is the main portion of the schedule timeout function:

        expire = timeout + jiffies;

        init_timer(&timer);
        timer.expires = expire;
        timer.data = (unsigned long) current;
        timer.function = process_timeout;

        add_timer(&timer);
        schedule();
        del_timer_sync(&timer);

        timeout = expire - jiffies;

Look into pfinet/timer-emul.c for the timer functions, and
glue-include/linux/sched.h for schedule().

Thanks,
Marcus
