Subject: [ruby-dev:10985] httphead.rb proxy version problem

小松です．

テストセットに使っている，[ruby-list:22001]のproxy対応の
httphead.rbですが，Ruby 1.6.0でハングするようになってしまいました．
netとrubyのどちらの問題でしょうか？

以下の例では，^Cで止めています．

% ruby -v httphead.rb http://www.ruby-lang.org/ja/index.html

1.4.6ではこんな感じでした．

[ruby-list:22045]のデバッグ出力版で動かすと，ヘッダが返ってきた
ところで待ちに入っているようです．
