On shutdown the plugin raises IOError

teardown 時の logstash-input-github/lib/logstash/inputs/github.rb の shutdown パスから始め、次にレポートに示されている ftw/server.rb と ftw/webserver.rb の stop frame を比較します。提供された bin/logstash コマンドを再現する前に、#2 と jordansissel/ruby-ftw#25 を確認します。プラグインを中断しても IOError: closed stream が発生しなくなれば完了です。

First found in #2, and is caused by jordansissel/ruby-ftw#25

bin/logstash -e "input { github { port => 3333 } }"
