Let's test Charles-Francois option.

> test_timeout_rounding failed because once EPollSelector.select(timeout=0.0099) took dt=0.0086 seconds

We asked to wait 9.9 ms, which was rounding to 9 ms. But epoll_wait() took 8.6 seconds: 8.6 is smaller than 9 ms.

In my opinion, rounding away from zero is not enough. We should probably round away from zero for selectors *and* compare times using the granularity.

Let's see what buildbots say :-)
