By the way, you can use boost::serialization::array to serialize 
contained data.
http://www.boost.org/doc/libs/1_39_0/libs/serialization/doc/wrappers.html#arrays

And, is it really needed to serialize capacity? (named "count"?!) I 
think it's unnecessary thing. Boost.Serialization library does not 
serialize capacity for standard containers.
