> os_thread_yield_other() function on Linux uses sem_timedwait() to wait for response from SIGUSR2 handler.
> It passes time interval =1ms to sem_timedwait(), but by documentation sem_timedwait() receives not time interval, but absolute time since 1970, so now sem_timedwait() always returns ETIMEDOUT immediately.
> It's required to calculate timeout exceed absolute time by adding needed interval to current time returned by gettimeofday() or clock_gettime(CLOCK_REALTIME).
> I've tried clock_gettime(CLOCK_REALTIME), it works fine.
> I'm going to provide a patch soon.
