Log message:
        * many, many files: several memory optimizations were implemented to
        drastically reduce the heap usage of FreeType, especially in the case
        of memory-mapped files. The idea is to avoid loading and decoding tables
        in the heap, and instead access the raw data whenever possible (i.e.
        when it doesn't compromise performance).
        
        This had several impacts: first, opening vera.ttf uses a ridiculous 
amount
        of memory (when the FT_Library footprint is accounted for), until you 
start
        loading glyphs. Even then, you'll save at least 20 Kb compared to the 
non
        optimized case. performance of various operations, including open/close
        has also been dramatically improved.
        
        More optimisations to come. The auto-hinter eats memory like crazy? This
        must be stopped...
