I think the problem here is, new says that it will force a heap 
allocation for its call. But the heap allocation shall not happen per 
delegate, it shall only happen once for the surrounding stack frame if 
it contains at least one heap allocated delegate.
hm, is it understandable what i mean by this ? :)
