+Alexander Cherepanov discovered that 7zip is susceptible to a
+directory traversal vulnerability.  While extracting an archive, it
+will extract symlinks and then follow them if they are referenced in
+further entries.  This can be exploited by a rogue archive to write
+files outside the current directory.
+
+We have to create placeholder files (which we already do) and delay
+creating symlinks until the end of extraction.
+
+Due to the possibility of anti-items (deletions) in the archive, it is
+possible for placeholders to be deleted and replaced before we create
+the symlinks.  It's not clear that this can be used for mischief, but
+GNU tar guards against similar problems by checking that the placeholder
+still exists and is the same inode.  XXX It also checks 'birth time' but
+this isn't portable.  We can probably get away with comparing ctime
+since we don't support hard links.
