You'll be glad to know that all going according to plan, we'll be able
to remove this dependency from the RTS before too long.  We're planning
some changes to the tail-call mechanism that means stack-walking will no
longer need to be able to distinguish between code and data pointers.

We're definitely interested in doing this.  BTW, swearing at Glasgow
won't get you very far, since we're in Cambridge :-p
