Subject: [ruby-dev:30593] [BUG] waitpid for ruby-trunk

けいじゅ＠いしつかです.

こんどは, ruby-trunk(ruby 1.9.0 (2007-03-14 patchlevel 0)[i686-linux]) 
の方のバグを報告します.

下記スクリプトを実行すると, 即座に

  #<Errno::ECHILD: No child processes>

が発生します. 


-- cut here --

p1 = fork{sleep 10}
p2 = fork{sleep 10}

Thread.start{
  begin
    puts "wait p#1"
    _pid = Process.waitpid(p1, nil)
    puts "end p#1"
  rescue
    p $!
  end
}

Thread.start{
  begin
    puts "wait p#2"
    _pid = Process.waitpid(p2, nil)
    puts "end p#2"
  rescue
    p $!
  end
}

sleep 20
