+12.    Extract dumped UNIX sockets as dummy files, instead of not
+       restoring them at all. This will correct some warnings during
+       the restoration of incrementals, if the inodes previously occupied
+       by sockets gets reused by other files. See Sourceforge bug
+       #3007216 for details.
