パッチを添付し忘れました。

修正方針ってこれで良いものでしょうか?

- LOAD\_PATHのエンコーディングはどうするべき?  
-E を考慮したdefault\_externalか、それともlocale encodingを強制するか

- prelude内でのIOはどれほど許される?

- なぜこんなに早いタイミングでpreludeが実行されてるんでしょうか?

- rb\_prognameをrb\_gc\_register\_mark\_objectしていましたが、rb\_prognameはあ  
とから上書きされているのでこちらもrb\_gc\_register\_mark\_objectしないとまずい?
