To kick things off, here is the big system that I work on:

    Files:          3  * 10**4
    lines of code:  1  * 10**7
    binary size:    5  * 10**6  up to 4 * 10**7 bytes
    Workers:        4  * 10**3  known to system
		    2  * 10**3  actually changing code 

The system is written in PROTEL and the operating system is SOS. In fact,
SOS is part of this system. This started off on propietary hardware and is
now running on several hardware platforms. This forms the "Central Computer"
of the DMS telephone switching sytems.

There are several more millions lines of code in the peripherals. The
peripherals are 8080, ..., up through 68020. Typically, these peripherals
form a hierarchy of four or more levels totalling thousands of processors.

These number are probably right, at least to one significant figure. But then,
there is no warranty.
