MMTk Bindings
Document the MMTk Bindings JNode concept in the wiki.
Value: 5
Concept Summary
Memory Management Toolkit VM interface for GC implementation. MMTk Bindings provide the integration between JNode's VM and the Memory Management Toolkit (MMTk), enabling sophisticated garbage collection strategies.

Instructions
Skill to Use
Use the [[update-wiki|update-wiki skill]] (load with skill({ name: "update-wiki" })) for understanding JNode internals.
Context Research
Review VM.java, Plan.java, and Space.java to understand MMTk integration. Study how MMTk's GC strategies are integrated with JNode's VM, how memory spaces are defined, and how GC plan selection works. Research the MMTk API and how it's adapted to JNode.

# MMTk Bindings
> Memory Management Toolkit VM interface for GC implementation.
## Overview
2-3 paragraph explanation of MMTk Bindings, how JNode integrates with MMTk, and how sophisticated GC strategies are enabled.
## Key Components
| Class / File | Role |
|---|---|
| `core/src/mmtk-vm/org/jnode/mmtk/VM.java` | VM interface to MMTk |
| `core/src/mmtk-vm/org/jnode/mmtk/Plan.java` | GC plan interface |
| `core/src/mmtk-vm/org/jnode/mmtk/Space.java` | Memory space definition |
## How It Works
Explanation of how MMTk integration works, how GC plans are selected, how memory spaces are managed, and how GC is triggered.
## Gotchas & Non-Obvious Behavior
- MMTk integration must be careful about VM state
- GC plans can be complex with multiple spaces
- Allocation patterns affect GC performance
