> Reproducible (thanks to Jeffrey Wang) by: 
> Create a CF with gc_grace_seconds = 0 and no row cache.
> Insert row X, col A with timestamp 0.
> Insert row X, col B with timestamp 2.
> Remove row X with timestamp 1 (expect col A to disappear, col B to stay).
> Wait 1 second.
> Force flush and compaction.
> Insert row X, col A with timestamp 0.
> Read row X, col A (see nothing).
