Hi Adam
As following your point, the benefit of boost::container::vector supported the "default_init_t" method so that it 's quite convince and safety comparing with std::vector<>
is that right ? are there additional advantages ? 

Hi Ilja 
You said "Boost::mpi version is always at least 10 times slower. " make me confused, I guess it's should be a typo, isn't ?
