+	Make sure to decrement connection counter before
+	calling connection notifier so that
+	MHD_DAEMON_INFO_CURRENT_CONNECTIONS does not
+	present stale information (relevant if this is
+	used for termination detection of a daemon
+	stopped via MHD_quiesce_daemon()). Thanks to
+	Markus Doppelbauer for reporting. -CG
