Zusammenfassung:A mechanism is provided for isolating application-specific data in an environment where multiple applications share a same user account. This mechanism enables data specific to an application to be accessed only by the application. When an application requests application-specific data, the data is loaded and a handle to the data is returned to the application. Access to the data is allowed only though the handle. Therefore, only the application possessing the handle can access the data. A counter may be associated with the loaded data. The counter's value is incremented whenever a handle is created for the data and decremented whenever a handle for the data is terminated. When the value of the counter reaches zero, the data is automatically unloaded.
