+  Notes:
+  On some systems dropping root capability allows the process to be
+  dumped, traced or debugged.
+  If someone traces this program, they get control of a raw socket.
+  Linux handles this safely, but beware when porting this program.
+
+  An alternative to needing 'root' is using a UDP broadcast socket, however
+  doing so only works with adapters configured for unicast+broadcast Rx
+  filter.  That configuration consumes more power.
