The more I look at the code, the more I'm getting confused...
Suppose that posix_timer_event()->send_sigqueue() increments info.si_overrun.
But (in general) it is not reported to the user-space, do_schedule_next_timer()
does:
info->si_overrun = timr->it_overrun_last;
shouldn't it do
info->si_overrun += timr->it_overrun_last;
instead?
