;; (load "gprof.o")
;; You must have a kcl image with profiling information and monstartup
;; typically saved_kcp. NOTE: if monstartup calls sbrk (true in
;; most 4.3bsd's except sun >= OS 4.0) you must be very careful to
;; allocate all the space you will use prior to calling monstartup.
;; If subsequent storage allocation causes the hole to move you will
;; most certainly lose. See below for instructions
;; on how to construct saved_kcp.
;; If you want function invocation counts to be kept do
;; (setq compiler::*cc* (concatentate 'string compiler::*cc* " -pg "))
;; before compiling the relevant files. (This is done when you load
;; lsp/gprof.o)
;; In the image saved_kcp Load in your files. Load in gprof.o: (load
;; "lsp/gprof.o") Invoke monstartup once to setup buffers: (monstartup
;; lowpc highpc) eg. (monstartup #x800 3000000) [highpc should be a bit
;; bigger than the highest address you have seen when loading your files]
;; Use moncontrol to toggle profiling on and off: (moncontrol 0) to turn
;; profiling off, and (moncontrol 1) to turn it on. Use
;; (wrtie-gmons+syms) to terminate with writing a gmon.out and syms.out
;; in the current directory. I know of no way of clearing the buffers,
;; since secret routines set up the buffers, and we don't know where they
;; are or how large. Thus all information is cumulative.
;; % gprof syms.out
;; will display the output (add -b) to make it briefer.

by (parent) call_or_link (the setting up of the fast link). Foo
itself calls (child) make_cons 200 of the 203 times that make_cons is
called... Lower down we would see that goo is called twice.
