But this code is looping in user space and should not make many. Why do 
you think it will make
many in this case?

In its runtime library interaction with system services - yes. This 
example is compute
bound in user space.

How is the code generation 'better optimized for linux' such that the 
generated code for
this source will be different? Doesn't make sense to me.
