    Original message:
    
    [heap] Divide available memory upon compaction tasks
    - Fairly (round-robin) divide available memory upon compaction tasks.
    - Ensure an upper limit (of memory) since dividing is O(n) for n free-space
      nodes.
    - Refill from free lists managed by sweeper once a compaction space becomes
      empty.
    
    Assumption for dividing memory: Memory in the free lists is sparse upon starting
    compaction (which means that only few nodes are available), except for memory
    reducer GCs, which happen in idle time though (so it's less of a problem).
