Thread-safe map

For a map to run optimally in a multi-threaded environment, when multiple occurrences of the map are instantiated, none of the resources that an individual instance of the map uses can be used by another instance of the map.

By default, map resources are managed. This helps facilitate the concurrent running of maps. However, you should specify unique names for the map's work files, audit logs, backup files, and trace logs, within each instance of the map.
