Bug #5577: test/testunit/test_parallel.rb causes NoMethodError when file
descriptor is limited to 30.

ulimit -n 30 として、file descriptor を 30個に制限した状態で、
test/testunit/test_parallel.rb をテストすると以下のように失敗します。

失敗する事自体は問題ではないのですが、
undefined method close' for nil:NilClass (NoMethodError) NoMethodError: undefined methodchomp’ for nil:NilClass
などと存在しないメソッドを呼んでしまっているのはよろしくないのではないでしょうか。

失敗の原因がわかるメッセージが出ると良いのではないかと思います。

とりあえず根本の原因である worker の起動に失敗したときはエラーメッセージを表示して exit 1 するようにしました。 (r34968)

は治す前から OS X だと刺さって

while _io=IO.select(@ios)[0] の行で動作が止まり終了してくれない状態です。
p @workers の出力 [15463:waiting] は、 Worker#to_s の出力で “pid:状態”
というフォーマットになっており、
pid 15463 で waiting の状態 (worker が起動した後最初に worker が出力 ready
という文字列を待っている状態) である事がわかります。
また @ios@workers.map(&:io) で、worker プロセスとのパイプ (IO.popen で生成)
の配列になっています。

^C する前に別のターミナルで ps 15463 して確認すると既に worker が終了しているので、
何故 @ios に含まれる IO に EOF が来ないか、というのを調べています。
