Subject: [ruby-dev:45352] [ruby-trunk - Bug #4434][Feedback] make test-all "-j10000" のように大きな並列数を与えると異常終了


Issue #4434 has been updated by Shota Fukumori.

Status changed from Assigned to Feedback

r34968 の変更で IO.popen による worker プロセスの起動に失敗した時に

>ERROR: Failed to launch job process - Errno::EMFILE: Too many open files - ./miniruby

と表示されるようになったので make test-all TESTS="-j10000" で現在チケットに書いてあるような
分かりにくい異常終了の仕方にはなってないのですが問題無いでしょうか。

(-j10000 は手元の環境じゃ too many open files になるというのもあり、引き続き再現するか不明
なので一旦 feedback にします)
