Well my typical code looks more like

load(...) {
   ifstream is("myfile");
   binary_iarchive ia(is);
   my_data d;
   ia >> d;

   return;
}

with the first try block "miles" away from the call. With a whole lot of 
layers in between. Layers which may or may not invoke threads.

The use you don't see is that I can do this. By not using boost 
exception you force me to take extra care either everywhere I use 
serialization or everywhere I use threads.
Its not much work, but it still inhibits a much cleaner abstraction level.
