Another detail I forgot about this point: there may be a memory leak on
variables copies, ISTM that the "variables" array is never freed.
I was not convinced by the overall memory management around variables to
begin with, and it is even less so with their new copy management. Maybe
having a clean "Variables" data structure could help improve the
situation.
