Hi all

I just added
Object class>>new
	^ super new initialize

and

Object>>initialize
	^ self

and run the macro benchmarks before and after:
Here are the results without **any** other changes in the system, which 
means that
there may be  double initialize.

Note that I remove the benchmark 5 as it was 0
