Original issue's description:
> Reland of "[heap] Divide available memory upon compaction tasks"
>
> This reverts commit ec1046f9f8.
>
> 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).
