(From update of attachment 129815)
I just realized that this fix is inadequate. The reason why we were scanning the CodeBlocks even if they were not jettisoned is that they might become jettisoned later in the GC!

The correct fix is to have a separate mechanism for ensuring that a CodeBlock is only scanned once.  I will work on this...
