I didn't actually do any 'real' benchmarking for this, I just pointed 
out that the conclusions you were drawing from top were rubbish.

Andrew and Tobys memory benchmarks make sense and are much nearer what 
I'd expect.

1.5Mb more per process is much more reasonable than the 20Mb you were 
speculating initially.
