- Rework how we manage memory, since sourceUnused hook is neither available nor makes sense. Rather, do it based on interpreter detaches
- Let the DebugDocument manage its document and view. It also manages the content construction, and does it more locally, instead of torturing katepart with zillions of line ops.
- Also, always use katepart for viewer, not the default editor
- Lay the foundation for persistent breakpoints. Doesn't seem to work yet,though
