Printer accounting and cutoff from UNIX: is it possible?

First of all, not all UNIX systems "crash" if they run out of swap
space.  The program that's trying to, say, increase its data space may
get a "no can do" from "sbrk()" and have "malloc()" return NULL, but
that's a different matter. 

Second of all, the disk space usage he was referring to was for *files*,
not for *swap space*.  Most UNIX systems don't "crash" if they run out
of disk space for files, either....
