Yes, I'd expect the memory usage to decrease if you build with  
NO_MALLOC_EXTRAS, since redzone overhead is 32 bytes per object.  Do  
you see any evidence of unbounded X memory usage though?

Why not just append to CFLAGS in make.conf?  NO_MALLOC_EXTRAS is a  
development-only flag, since the malloc debug features will be  
disabled for releases, so a make.conf knob would have no relevance to  
releases.  Unless there's serious worry about cpp namespace  
pollution, I don't understand the need for the patch you provided.
