This can only occur if they aren't marked, but are ggc allocated. They
shouldn't be, if they are.

It is wrong.
They will *always* be collected if this is the case.
It must not show up because we push context before starting our
PRE'ing of expressions, so unless we redo dom children, we'd not collect
them.
