Cheriton, D.R., Malcolm, M.A., Melen, L.S., Sager, G.R., "Thoth, a portable real-time operating system", Communications of the ACM, 22, 2, pp. 104-114, February 1979. Google
105 ;;Quote: Thoth guarantees worst-case times for responding to interrupts
105 ;;Quote: Thoth is the first operating system designed for portability
106 ;;Quote: under Thoth a function is either invoked as a subroutine using the current stack, or as a process with its own stack
106 ;;Quote: Thoth's operating system includes memory management, messaging, multi-tasking, delays, and file I/O
107 ;;Quote: assign each process to a team with a shared address space and memory; communicate between teams with interprocess communication primitives
107 ;;Quote: Thoth has resident and transient teams of processes; transient teams swapped to secondary storage as needed
108 ;;Quote: Thoth's file system is a tree in which each node is a file
109 ;;Quote: a program is portable if it costs significantly less to modify it than to rewrite it for a different computer
113 ;;Quote: Thoth provides basic times for system calls and fixed, maximum times for disabled interrupts and device responses
