COW page

鬼車に対して、パッチ付きのメールが来た。

Because the data section is larger than 4096 bytes,
it means that every process that is linked to
liboniguruma.so needs at least two COW pages for global
writable data.

I'm trying to reduce the size of the data section to
less than 4096 bytes, so oniguruma only needs one COW page.

COW pageを一個に縮小できると、何がどの程度良くなるのか見当がつかないのだが、どうしたものだろう。
