 From where do you need access to those variables? From MapScript?

My main concern with this change is the amount of memory that will be 
allocated to temporarily store the values of all the expanded variables. 
  For instance the metadata variables can become quite large.  At the 
moment the same buffer is used for all the variables.

Since those variables just represent values already accessible in the 
mapObj from MapScript, could you not simply access the values directly 
in the mapObj?  (I guess if we understood what you are trying to do it 
would be easier to justify the change.)
