Summary:
If an object has overflow keys (note that MongoDB objects do not have overflow keys), bulk-load or rebalance can create huge, pinned root pages. This ticket changes that behavior, splitting the root page before it's written to disk.
The cache stuck with clean page issues are still happening after the merge of WT-4715.
