摘要： An embodiment of the present invention provides an efficient and robust way to facilitate interoperability between two or more processes which were initially written to execute on top of two different operating systems but instead execute on top of a third operating system. Typically, the preferred embodiment begins by launching a parent process which was initially written to execute on top of a first operating system. The preferred embodiment then obtains a context object that implements a naming graph for the parent process. The context object includes bindings between a given set of names and an associated set of objects that are specific to the first operating system. At some point during execution of the parent process, the parent process spawns a child process which was initially written to execute on top of a second operating system. Next, the parent process instantiates a copy of its context object. The parent process then performs a context merge operation which ensures that object names used by the second process are interpreted relative to a context object associated with the second operating system before (or in lieu of) being interpreted relative to the context object for the first operating system. Once the context merge operation is complete, the new context object is passed to the child process and execution of the second process begins. System calls initiated by the child process will therefore be interpreted relative to the name space for the second operating system. In this way two processes which were initially written to execute on top of two different operating systems can interoperate while executing on top of yet a third operating system.
