In which sense is that different? AFAIK select lets you avoid polling
and provides notifications (possibly with timeouts) for IO-events. So
where exactly is the difference? I read TFA, and it does mention that
select/poll have potential for optimization, but not something that
disqualified them (or rather select) as being not async.
