While you're at it, I heard once that the latest GCC *manual* (>500 pp at last look) was larger than "the whole Unix distribution". Is there any truth to that?

You might find http://stromberg.dnsalias.org/~strombrg/working-set/ interesting.

It intentionally fills virtual memory, and measures how much must must
be malloc'd and filled with gibberish, to cause thrashing.

Subtracting that from the amount of physmem in the machine, gives a
sort of measure of OS overhead.
