Referring to your description:

"I have
a 22-line (C) init program that does nothing but run the boot script
and reap orphaned zombies, and a 34-line (C) program that repeatedly
re-runs a program in a new session every time it exits. The latter,
combined with a 14-line (shell script) getty program, is sufficient to
handle all console logins.
"

it's a bit more then 22 LOC :)
