This is Lisp on the IBM 704/7090 and PDP-1 in 1960-1964. Ritchie would not start work on C until 1969 and there was no standard C library (which, btw, is completely irrelevant to the runtime state of a process) for decades. There were no processes or virtual memory (the 7090 didn't even have overlays) or non-Lisp stuff other than the punch card/paper tape loader.
