Abstract
An operating system kernel includes an attach mechanism and a detach mechanism. In addition, processes are tagged with an access attribute identifying the process as either a client process or a server process. Based on the access attribute, the operating system kernel lays out the process local address space differently depending on whether the process is a client process or a server process. A server process can 'attach' to a client process and reference all of the client process' local storage as though it were its own. The server process continues to reference its own process local storage, but in addition, it can reference the other storage, using the client process' local addresses. When access to the other storage is no longer needed, the server process can 'detach' from the client process. Once detached, the other storage can no longer be referenced.
