When calling a Recv/Alloc/Dealloc method on most types, cast `this` to the derived class. There is a heuristic to figure out what the correct derived type is. There is a blacklist of types which we can't do direct calls on for the moment, as well as an override for types that do work with direct calls but which don't match the heuristic.
