This is similar to what physics baking is doing: invoking the operator runs a background job, whereas executing blocks. This makes Python scripts calling the Alembic import/export operators more predictable. For backwardward compatibility with existing Python code the `as_background_job` parameter still exists, which overrides the behaviour chosen by INVOKE/EXECUTE.
