| 39 | * Garbage Collector has to synchronize the GC head's write buffer before | ||

| 41 | * actually reclaim even very small pieces of dirty space by garbage collecting | ||

| 46 | * if GC move data from LEB A to LEB B and nodes in LEB A are large, GC would | ||

| 48 | * from LEB A would not fit. And the worst situation is when all nodes are of | ||
| 49 | * maximum size. So dark watermark is the amount of free + dirty space in LEB | ||
| 50 | * which are guaranteed to be reclaimable. If LEB has less space, the GC migh | ||
| 51 | * be unable to reclaim it. So, LEBs with free + dirty greater than dark | ||
