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/

 It intentionally fills virtual memory, and measures how much 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.
