Yes, see the other mail. The reason is that the allocation of contexts
in case of blocks happens now at #value, whereas it used to be just done
at the definiton point (#blockCopy).
So nothing to worry about.

Yes, and the real solution of course is to change the VM to allocate

contexts and use the C-stack instead...
