See man 3 mallinfo.  In short,
   arena is tha amount of malloc'ed memory from sbrk-allocated area
   mmap is tha mount of mmap-ed memory (malloc uses mmap(/dev/zero)
    for larger requests
   free is the amount of memory in internal malloc structures which
    is requested from the OS but isn't used by the program (eg the
    memory wich was free()d but not yet used by subsequent malloc()).
