Comment # 1 on bug 1204695 from Martin Doucha

The test was recently rewritten but it appears that it found a kernel bug. I've
modified the test to print the wrong values returned by setitimer() in the
third parameter and tried a few experiments with different timer values. The
experiment works like this:

new_timer = old_timer = {0};
new_timer.it_value.tv_usec = 9234;
setitimer(type, &new_timer, NULL);
new_timer.it_value.tv_usec = 10345;
old_timer.it_value.tv_usec = 18456;
setitimer(type, &new_timer, &old_timer);

Here we check that old_timer.it_value.tv_usec < 18456 and fail because the
kernel sets it to 19234. I've tried multiple value combinations and the kernel
always set old_timer to 10000us more than it should be when the timer type is
ITIMER_VIRTUAL or ITIMER_PROF. ITIMER_REAL appears to work correctly.
