This should be a test case for the marshaling improvements.

The interop API is being reimplemented and this will not to fit in 7.0.

I believe that Task which are proxies for JS Promise are not lightweight object and it's not clear to me if they could be.
I think we should delete the disabled tests and close this issue.
