Here's an example of the sort of thing I'm trying to avoid: foo is a symlink to bar bar is a symlink back to foo readlink() on either one will succeed, but I'll end up with infinite recursion because I'll resolve foo to bar, then bar to foo, then foo back to bar, etc. To avoid craziness like this the OS refuses to follow a chain of more than a very small number of symlinks. By experimentation, I found the limit to be 8 on my Linux box. I am trying to avoid resolving symlinks manually that the OS would refuse to resolve anyway. However, I'm quite open to suggestions for a better way to do it.
