Subject: [PATCH] Race condition in object model, further debugging needed

This debugging code helps debugging a race condition in the object model.

This seems to be observable rather reliably with accesses to cached class fields.

Specifically, we can see that in Parser.ns, we read the slot `R`, and retrieve an `A class` instead of `R class` rather reliably.

Truffle Specializations do not automatically have exclusive semantics. Instead, the rules of the Java type system apply.

Let's take the following node with three specializations as example. Note, I return an int here, usually you'd return a boolean, but the int allows me to get the point across more precisely in the later tests.

@NodeChild(value = "e", type = ExprNode.class)
public abstract class IsNumberNode extends Node {
