your analysis "should" be incorrect. the regions pointed to by the
region list are not present in any playlist (they are copied by the
session before being pointed to).

1) using any part of boost generally requires using all of boost
2) this was designed not to be a shared_ptr-using system for reasons
      indepedent of lifetime issues. the whole question of what 
      actually happens when you edit a region makes it necessary
      to make the region list objects be 100% distinct from those
      found in playlists.
