摘要：
A method and apparatus for extending a tenure of a process that owns a system process that has shared data or resources and also is requesting the owned system process. The ability to extend the tenure of the owning process allows the nesting of requests to the system process. By properly ordering how the requests are nested, deadlocks may be avoided. Additionally, by extending the tenure of a current process, some unnecessary changes in processor instructions and data may be avoided and processing efficiency increased.
