I understood that that other LFN usage was also commented out.

I'm not sure: if you comment out _is_executable, you don't read the
file, but you still lseek (because fstat does that elsewhere in its
code, when it calls __filelength).  So the read-before-lseek
hypothesis should explain why seeking in __filelength works, while
seeking in _is_executable doesn't.
