+	Handle many simultaneous clients.
+	* src/server/connections.c (login_request): Don't handle the "% No
+	connections left" situation.
+	(toploop): Handle ISC_EVENT_LOGIN_UNRELOCATED by returning a "% No
+	connections left" message and closing the session, the way
+	login_request used to do.
+	* src/server/ramkomd.c (initialize): Warn if getrlimit and sysconf
+	don't agree on the number of possible open files.
