こんなとこですかねえ？ db3 で試しました。test_s_open_error 
が失敗するのは、Berkeley DB では同時オープンが許可されると言
う事なんでしょうね。これも書き換えた方がいいんでしょうね。

このテストで気がついたのですが(最後に添付した結果を見てもら
うとわかりますが)、最近の ruby では、Errno::EWOULDBLOCK がな
くなってます。(EWOULDBLOCK == EAGAIN の場合)

ruby -ve 'p Errno::EWOULDBLOCK'
-e:1: uninitialized constant EWOULDBLOCK at Errno (NameError)
ruby 1.8.0 (2003-01-18) [i586-linux]

ruby-1.6 -ve 'p Errno::EWOULDBLOCK'
-e:1: uninitialized constant EWOULDBLOCK at Errno (NameError)
ruby 1.6.8 (2003-01-17) [i586-linux]
