Various quotations found sprinkled about the source code for this PDP-11 operating system: https://cybre.space/@niconiconi/107101692082714219 (sorry dead link now, new profile here but I haven’t yet found the missing post)
Well, PDP-11 RT-11 Source code had extensive quoting from Gilbert&Sullivan to mark relevant sections, like:
Behold the Lord High Executioner
on the process dispatch code.
Actually, that comment (actually a full verse of the song) is for the code which handles program exits, if I remember correctly…
heck, let me consult the source…
from rmon.mac:
;+
; “Behold the lord high executioner!
; A personage of noble rank and title -
; A dignified and potent officer,
; Whose functions are particularly vital.”
; - W.S. Gilbert, “The Mikado”
;
; The following entry point is used to abort a running job.
; It switches to System State, sets the abort bit for the user,
; and falls into the abort code.

There are quite a few things in the RT sources… I posted a number of them someplace a few years ago, maybe I should collect them and make them available somewhere…
One of my favorites (other than the verse from The Mikado) is the comment for the code which moves the KMON (keyboard monitor) and USR (User Service Routines) up and down in memory as handlers are loaded and unloaded, or foreground or system jobs are installed or removed.

; “The awful shadow of some unseen power
; Floats, tho’ unseen, amongst us”
; - Shelley, “Hymn to Intellectual Beauty”
