By default, |object| takes a global write lock while evaluating the JavaScript function. As a result, |object| blocks all other read and write operations to the database while the |object| operation runs.

To prevent the taking of the global write lock while evaluating the JavaScript code, use the |nolockobject| with nolock set to true. nolock does not impact whether the operations within the JavaScript code take write locks.
