      Try to remove the checkpoint lock from the bulk cursor close path – can we switch to an atomic flag on the btree handle, set by both checkpoint and bulk close?

      At the moment, completing a bulk load grabs the checkpoint lock. This prevents multiple bulk loads from completing in parallel. Another way to address this would be to make the checkpoint lock into a read-write lock, but it would be better if we can avoid it altogether: each bulk load already has exclusive access to the tree it is building.
