The deadlock is caused by chained unload/load on locked blocks.

I'm working on a patch to solve this, essentially we don't want to load/unload other nodes while keeping current node lock and during merge/checkpoint we don't need to fully load merging blocks in page replacement policy memory, the will be discarded at merge end
