I'm not sure what the referent of "that" is. The statistics-gathering I've seen
seems to be all about writing line-at-a-time records to various stats files;
I can't see that generating a lot of memory pressure.

If there's somewhere in the code that is allocating memory proportional
to the size of saved statistics, yes that could be a problem.  Do you
have some specific case in mind?
