When I try to invoke method from intercepted class in multi-thread test sometimes I get following exception:
System.ArgumentException
Destination array was not long enough. Check destIndex and length, and the array's lower bounds.

Sample class that generates exception:

[TestFixture]
public class ExceptionExample
{
	static ExceptionExample()
	{
		Mock.Initialize<TestClass>();
	}

	public class TestClass
	{
		public void ExecuteSomething()
		{
			int y = 0;
			for (int i = 0; i < 100; i++)
				y += i;
		}
	}

	[Test]
	public void MethodName()
	{
		List<Thread> l = new List<Thread>();

		for (int i = 0; i < 6; i++)
		{
			Thread t = new Thread(RunMethod);
			t.Start();
			l.Add(t);
		}

		l.ForEach(th => th.Join());
	}

	private void RunMethod()
	{
		for (int i = 0; i < 10000; i++)
		{
			TestClass tc1 = new TestClass();
			tc1.ExecuteSomething();
		}
	}
}

Current behavior:
Mock.Arrange(xxx).IgnoreInstance();    //mock all future instances of the type on which I set an expectation.


Feature Request:
Mock.Arrange(xxx).IgnoreInstance().Next();    //mock the next instance of the type on which I set an expectation.

...and even better...

Mock.Arrange(xxx).IgnoreInstance().Skip(3).Next();   //mock the 4th instance of a type on which I set an expectation.

Currently, I can only assert all when automocking.  It would be nice to be able to assert individually.  container.Assert<IAccount>().  If we implement my other item (http://feedback.telerik.com/Project/105/Feedback/Details/850-distinguish-between-automocked-items-when-multiple-of-the-same-are-in-the-constru) then it would be container.Assert<IAccount>[0] if there were more than one IAccount in the constructor.

If I have a constructor like this: public Foo(IAccount fromAccount, IAccount toAccount) { //code }, I need to be able to distinguish between the two accounts when automocking.
container.Arrange<IAccount>() won't work.  Perhaps container.Arrange<IAccount>[0] would. 

As a developer, I want to be able to automock classes that have concrete classes injected
