Abstract: Methods and apparatuses for proxying communication requests to services hosted on a data processing system. In one exemplary method, an open-ended configuration file is distilled to create an object tree from the configuration file. In addition, distillation creates communication handles for the services. The object tree is serialized and forwarded to a proxy agent. The proxy agent registers the service and monitors the communication handles for service requests by establishing a kernel callback. When a communication handle is readable, the proxy agent passes the communication handle to appropriate service.

Abstract: An efficient mechanism for terminating applications of a data processing system is described herein. In one embodiment, in response to a request for exiting from an operating environment of a data processing system, an operating system examines an operating state associated with an application running within the operating environment, where the operating state is stored at a predetermined memory location shared between the operating system and the application. The operating system immediately terminates the application if the operating state associated with the application indicates that the application is safe for a sudden termination. Otherwise, the operating system defers terminating the application if the operating state associated with the application indicates that the application is unsafe for the sudden termination.
