 Per [https://tahoe-lafs.org/pipermail/tahoe-dev/2012-April/007233.html
 this mailing list discussion], a better way to detect cycles than counting
 how many symlinks you've traversed is to examine the dev and inode of each
 thing and raise an exception about recursive symlinks if you encounter the
 same one a second time. Here's some code I wrote for a different tool that
 uses dev and inode to identify files:
