The usual way to handle this problem is with a HAL - a hardware abstraction layer.
It is also called a microkernel - kind of like a layer between a BIOS and the OS, like what Linux does.

If you go to Dissertation Abstracts, you will find a lof of Master's Thesis that did exactly that - a microkernel. You may even find one for the version of Unix your Dad is running.

Try googling for 'unix microkernel' to start off. In the late 70's we had tapes from Bell Labs: you built C first, then compiled the OS.

SPEEDY_BACKEND(1p)														SPEEDY_BACKEND(1p)

NAME
speedy_backend - the backend process for a persistent Perl interpreter SYNOPSIS
none ; this program is not meant to be called directly. DESCRIPTION
speedy, short for SpeedyCGI, is a way to run perl scripts persistently, which can make them run much more quickly. After the script is initially run, instead of exiting, the perl interpreter is kept running inside a backend process, speedy_backend. Dur- ing subsequent runs, this interpreter is used to handle new executions instead of starting a new perl interpreter each time. A very fast frontend program, speedy, written in C, is executed for each request. This fast frontend then contacts the persistent Perl process, which is usually already running, to do the work and return the results. Each perl script runs in its own Unix process, so one perl script can't interfere with another. Command line options can also be used to deal with programs that have memory leaks or other problems that might keep them from otherwise running persistently. The speedy front end connects to the back end process, speedy_backend, via a Unix socket in /tmp. A queue is kept in a shared file in /tmp that holds an entry for each process. In that queue are the pids of the perl processes waiting for connections. The frontend pulls a process out of this queue, connects to its socket, sends over the environment and argv, and then uses this socket for stdin/stdout to the perl process. FILES
/tmp/speedy* A unix socket used to connect to the frontend process. AUTHOR
