が怪しい。
さとる氏が勧めてくれたMallocDebugを眺めていると、
WebViewがURLを食うたびに、
[NSView _recursiveDisplayRectIfNeededIgnoringOpacity:isVisibleRect:rectIsVisibleRectForView:topView:]
が生成される。しかもメガ単位。
これを解決すれば、メモリ問題はとりあえず終息。
しかし、WebCoreまではやりたくない。

今日は、ヘッダをとった。
そこからどういじろうか？
実は、オンラインで潮汐表が公開されているので、（たしか海上保安庁が実測値をアップしている）
ヘッダの最終更新日時の潮位をとってきて、波に反映なんてこともできる。
（やるかどうかは別だが）
