+              On Windows this option will be ignored unless
+              <c><anno>Socket</anno></c> is an UDP socket. This since the
+              behavior of <c>reuseaddr</c> is very different on Windows
+              compared to other system. The Windows behavior makes its use
+              dangerous, and there probably are no useful use-cases in the
+              non-UDP cases either. However, in the UDP case on Windows there
+              are useful use-cases.
