We sure don't provide much help for such an administrator. (Happily,
I am not one.) The instructions for Linux offer a configure recipe
and says "it might work." If you build without large file support on
a Linux system, the test suite gives no indication that something went
wrong. So I think it is unreasonable to say the Python install is
broken, despite the fact that it's possible to do better.

os.path.exists() is perhaps the most egregious. I think it's worth
backporting the fix to the 2.1 branch, along with any other glaring
errors. We might still see a 2.1.4.
