Can't use Console.WriteLine in PoseContext

[asherber]

I'm not sure if this is related to #14 and #15, or if it's maybe just user error.

I was taking Pose for a quick test drive and created a shim for DateTime.Now and then tried to output it, but the app threw an exception. Then I took out any use of the shim from within the isolation, and I'm still getting an error. IOW, it seems that just calling Console.WriteLine() from within an isolation context throws an exception.

Sample code:

static void Main(string[] args)
{
    var shim = Shim.Replace(() => DateTime.Now).With(() => DateTime.Parse("2000-01-01"));

    PoseContext.Isolate(() =>
    {
        // originally had Console.WriteLine(DateTime.Now)
        Console.WriteLine("foo");
    }, shim);

    Console.ReadLine();
}

Exception:
