Subject: [ruby-dev:45422] [ruby-trunk - Bug #4434] 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 kosaki (Motohiro KOSAKI).


Too many open files を出してるのがマネージャープロセスなら、しょうがないんじゃない。それはRLIMIT上げればいいんだし。
workerプロセスが出してるなら問題で、それはfdリークを意味してるので -j の数によってテストが変わってしまう可能性があるのでよくないよね。
