+ <note>
+ 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.
