> When init 'CellChunkImmutableSegment' for 'COMPACT' action, we not force copy
> to current MSLab.
> When cell size bigger than maxAlloc, cell will stay in previous chunk which
> will recycle after segment replace, and we may read wrong data when these
> chunk reused by others.

> Timeline:
> # add a cell 'A' bigger than 256K
> # cell 'A' will copy to a chunk 'A' when first compact
> # cell 'A' will retain in chunk 'A' when second compact
> # chunk 'A' recycled after segment swap and close
