Abstract
In a single-process/multithread environment, a thread group is prepared for every application, the application is started on the thread belonging to this thread group. When a certain thread accesses a different thread, this access is trapped and rejected if these threads do not belong to the same application thread group. This scheme, when a plurality of applications is run on different threads, prevents parameters etc. within the application from being changed by other applications.
