1. In a computer system, a method for providing for concurrent subprocessing of a master process, the method comprising the steps of: interfacing a master process with a user-specific process that mirrors an interface for the master process when a user-specific operation is encountered; mapping the user-specific process with a virtual memory separator so that it overlays virtual addresses of the master process; processing the user-specific operation in the user-specific process; and transferring data between the master process and the user-specific process using a communications channel that does not require the serialization of data.
