How about flush()?  I implemented such a thing back in 2005:

  http://lists.boost.org/Archives/boost/2005/03/81544.php

I would still find it useful, I have a lot of code that relies on 
anonymous scopes to control construction/destruction of archives, 
the code would look a lot more straightforward if I could just flush().
The use case is can be modeled the same was as sending packets over 
the network.  Each packet needs to have internal pointer tracking, but 
independent of the others.
