+If this flag is enabled, whenever a client sends a DHCPREQUEST for a
+particular lease, the server will automatically free any other leases
+the client holds.   This presumes that when the client sends a
+DHCPREQUEST, it has forgotten any lease not mentioned in the
+DHCPREQUEST - i.e., the client has only a single network interface
+.I and
+it does not remember leases it's holding on networks to which it is
+not currently attached.   Neither of these assumptions are guaranteed
+or provable, so we urge caution in the use of this statement.
