We don't follow symlinks (since we generally use os.lstat), so a cycle
wouldn't do anything.

strace might work, but it would mean parsing the output, and I don't
know if strace is stable on all platforms.

It also requires having strace available, and I know it isn't on my Mac
(it might be a simple port install away, though).

Since we don't seem to have a better way, do you have a vote for the patch?
