[Mono-list] AppDomain

[Torstensson, Patrik]

Ignore my previous post how to fix the problem. The obj->vtable contains
raw pointers and not methods. I think we should handle the tp case in
the runtime invoke method.. 

(I'm taking out my clown kit an putting it on today, I'm today's clown.
:-)

Cheers,
 Patrik
