thanks a lot.
so as i undestand, the real_used_size is the right value to calculate size.
but, it grows because of fragmentation data.
in the core, what does it mean "It is effective if MEM_JOIN_FREE compile
option is defined"
is there something else i need to do except adding to the cfg the
mem_join=1 ?
