Motivation: It's possible for fdopendir(3) to return 0 if the file descriptor's backing filesystem is force-unmounted. This should return an error, but instead crashes the library. Result: If fdopendir fails, FileDescriptor.opendir will return the error contained in errno (set by the stat(2) call in libc fdopendir).
