144 ;;Quote: multi-programming needs meta-instructions for parallel processing, naming, and protection
144 ;;Quote: a computation proceeds within a sphere of protection as defined by a list of capabilities
144+;;Quote: a capability is a pointer to a computing object and the actions that the computation may perform on that object; e.g., segment capabilities for reading, writing, and executing
145 ;;Quote: a process is a locus of control, an abstract entity that moves through the instructions
145+;;Quote: a process is either active or it is suspended, awaiting activation by an external event such as I/O
145 ;;Quote: a list of capabilities defines a computation's protections
145+;;Quote: a capability is an ID for a computing object and the allowed actions
145 ;;Quote: a principal is an individual or group who is charged for system resources
147 ;;Quote: implement shared memory with a one-bit lock on each data object
152 ;;Quote: refer to objects via the index of a capability pointing to a directory
152+;;Quote: a hierarchical directory structure enables passing a subhierarchy to computations and principals
152+;;Quote: each principal has a root directory of retained objects
154 ;;Quote: the capability list came from the Burroughs B5000 program reference table
154+;;Quote: duplicating private data at a fork came from Witsenhausen
