// This error comes from the internal/poll package, which is also
// used by package net. Doing it this way ensures that the net
// package will return os.ErrDeadlineExceeded for an exceeded deadline,
// as documented by net.Conn.SetDeadline, without requiring any extra
// work in the net package and without requiring the internal/poll
// package to import os (which it can't, because that would be circular).
