This seems to be a somewhat opaque area in the documentation.

Have you tried testing the return value of closedir? If it reports a failure, that is probably indicative of a failure in the readdir call. Of course, I don't have a good way of testing this, either.

Also, it is good practice to use a lexically scoped variable for the directory handle rather than a bare word.
