  first: that isn't how GUILE is intended to be used.  second: I'm talking
  about actual memory consumed by the process for its _own_ data.  data or
  code that cannot be shared.  state information, whatever you want to call
  it.  I haven't see anyone refer to this as anything other than "heap",
  and I find it odd that you think such a heap should be sharable.
