System.Threading.Tasks.Parallel error in IronRuby

In C#

class ParallelTest
{
    public static void Main()
    {
        System.Threading.Tasks.Parallel.ForEach(new []{1,2,3,4,5,6,7,8},
                        x => { System.Console.WriteLine(x); }
                    );
    }
}

Result
4
5
6
7
8
2

3

But, in IronRuby(1.1.3).
Some line empty or lose linefeed.

System::Threading::Tasks::Parallel::ForEach([1,2,3,4,5,6,7,8], Proc.new {|x|
    puts x;
})

Result
1734

Is this just a bug?

It seems IronRuby's puts is not thread-safe. If you use Console.WriteLine() in IR, it works fine:

System::Threading::Tasks::Parallel::ForEach([1,2,3,4,5,6,7,8], Proc.new {|x|
    System::Console::WriteLine(x)
})
