And also I guess the compilers will do more optimisations, etc.
So this suggests an obvious extra feature for nobench which would be the 
ability to view a graph of each compiler's performance over a period of 
time, obviously this probably wouldn't be useful for at least a few 
months. However in particular it would be very good for the compiler 
writers to be aware if the performance goes *down* that is a further 
release of a compiler causes a benchmarked program to run slower.
