Since we don't track the current process using the sc_curr_proc_handle structure, we keep one around just to return from the appropriate accessor, and set its values when it's requested. If the object is kept around, those values won't change to track changing processes. From what I see, none of the tests rely on the value tracking the process beyond the callsight.
