Where do you propose we should add it? If it is right before the
second read, it will solve the problem with blocking forever, but
chronyd will still be unresponsive for the second which I'm worried
about more as it degrades NTP performance.
Note that read_from_device() is called only when select() says the
descriptor is ready, so adding a second select might not make the
results better.
