we can ignore the costs of the strings as
they should be fully shared, especially for BDW-DE.
Are you sure about this? I did not think that the compiler would have 
the intelligence to try to share strings. That is the basis of the size 
optimisation which I was proposing (that the compiler would not share 
strings).
JFYI, I am finding that all identical strings are shared, which is good.

Thanks,
John
