Josh Rosenberg added the comment: So would the goal of a fix be something like dev/inode memoization to prevent traversing the same link twice? To provide an argument to prevent following symlinks at all (as in stuff like os.walk), possibly defaulting to followlinks=False? It looks like languages like Ruby never follow symlinks when performing recursive globs to avoid this issue ( https://stackoverflow.com/questions/357754/can-i-traverse-symlinked-directories-in-ruby-with-a-glob ). It's probably easiest to just block recursing through symlinks (at least by default); memoizing risks unbounded memory overhead for large directory trees.
