The paper describes Grasshopper, an operating system designed to provide generic mechanisms capable of being tailored to support a wide range of persistence paradigms. A constraint placed on this design is that the system must be implementable on conventional architectures which support paged virtual memory. The basic system abstractions relating to addressing environments, processes, and protection are described. It is shown that these provide explicit support for distributed persistent objects and processes, stability, and access control. At the same time the system provides the flexibility to allow user implementation of alternative object management techniques
