<   - MongoFS as StorageDriver .transaction(trans, callback(err, result)) map should emit actions including the mapping for all files in the directory
<   - MongoFS as StorageDriver .transaction(trans, callback(err, result)) map should emit actions so that when sending the "tramp" actions back, we get mappings for all files in the sub-tree
<   - MongoFS as StorageDriver .transaction(trans, callback(err, result)) map should work whether or not the directory already exists
<   - MongoFS as StorageDriver .transaction(trans, callback(err, result)) map should propagate to future subdirectories
<   - MongoFS as StorageDriver .transaction(trans, callback(err, result)) map with put should cause subsequent puts emit the mapping for the new object
<   - MongoFS as StorageDriver .transaction(trans, callback(err, result)) map with put should cause puts that overrides an existing value provide mapping for the new value and unmapping for the old one
<   - MongoFS as StorageDriver .transaction(trans, callback(err, result)) map with remove should emit unmapping of the removed content
<   - MongoFS as StorageDriver .transaction(trans, callback(err, result)) unmap should remove the mapping with ts from path, and produce actions to undo its effect
