森脇です。

DebianでRubyをパッケージングしているのですが、ユーザから要望があったので、ちょっ  
とお尋ねします。

1.8.6あたりで、fastthreadがマージされてthread.cができたことと思います。しかし、  
そのユーザから、現在の1.8.6では"a couple serious bugs"があるので、それが既に修正  
されているfastthreadをパッケージングするなり（Rubyにパッチをあてるなり）して欲し  
いと言われています。

出典はここ[1]だそうで、

> Shortly, the waitlist structures could become corrupted

とあります。しかし、昨年の3月から5æœˆé ƒã®è­°è«–ãªã®ã§ã€ãƒã‚°ãŒãã®ã¾ã¾æ”¾ç½®ã•ã‚Œã¦ã„ã‚‹  
とも思えず、修正がRubyにマージ済み（または予定）なのであれば、fastthreadを別途  
パッケージ化する必要はなくなります。fastthreadとのシンクロ具合は、いかがでしょう  
か。thread.cのlogをみると、確かに2007å¹´3æœˆé ƒã«ã„ã‚ã„ã‚ã‚³ãƒŸãƒƒãƒˆãŒã‚ã‚‹ã‚ˆã†ãªã®ã§ã™  
が。または、実際に積み残しになっているようなknown bugがあるのでしょうか。

では。
