Scanning the stack is definitely not needed for the pdump since the
pdump itself does not include the stack.

So it's only needed if we want the interactive session to *survive*
the pdump.  I can see good reasons to let users create their own
heap-image, but I think the use-cases where it's important for the
session to survive the pdump are pretty hard to come by.
