Description

Right now, in the WiredTiger integration layer, we generate a new global cursor epoch and close all cursors that are returned to the cache on encountering a WT_BUSY attempting to drop a specific ident. Change closeAllCursors to only close cursors on the idents that require dropping.

This is expected to significantly help users with large numbers of collections.
