He didn't; select() isn't SA_RESTART-able.

Unfortunately, the author of select.select() decided to treat EINTR as an
error. It isn't; it's a "third way", neither success nor failure, similar
to EAGAIN. Normally, you would treat EINTR from select() in the same way
as a timeout.

While it's possible to work around this, the interface encourages getting
it wrong.
