[Boost-users] [serialisation] Yet another problem with non default constructors

I know from the doc that the way to deal with non default constuctors 
for deserialization is the load_construct_data function.

However, I'm in a case where the parameters of the non default 
constructor are not serializable, but can be provided at runtime. How 
can I pass those values to load_construct_data ?

One example to be clearer:

class Data
{
public:
     Data(Mutex &m) :
         myMutex (m)
     {}
private:
     friend class boost::serialization::access;
     Mutex &myMutex; // Mutex is intrinsically a non serializable info
     template<class Archive>
     void serialize(Archive &ar, const unsigned int file_version){
     }
};

int main()
{
     vector<Data> v;
     Mutex mutexForData = createMutex();

     std::ifstream ifs("filename", std::ios::binary);
     boost::archive::text_iarchive ia(ifs);
     ia >> v; // I'd like Data in the vector to use my mutexForData mutex
}
