And better still, it is platform specific too.

| These are the standard C operating system and file system error codes, 
| not Python exceptions.

And the poster boy example for platform dependence.

Besides, knowing the exact errors that may occur is not the Python Way, it is
the Java Way.

Run it. if it goes bang, handle the errors you expect and understand.
If you get something else, go bang for real because you _don't_
know what should happen, and proceeding is probably insane.
