+        Avoid deep recursion and file descriptor exhaustion.
+        1. unp_detach: go not call unp_gc directly for descriptors
+           that are unixdomain sockets themselves. Instead mark them
+           for cleanup during garbage collection.
+        2. unp_gc: handle detach of descriptors that were marked earlier.
+        3. prohibit transfer of descriptors within SCM_RIGHTS messages if
+           (num_files_in_transit > maxfiles / unp_rights_ratio)
