Hmm, yes, they do, but they also have a pitfall.  If I create a new
templated ostringstream with a custom allocator, it then means that
the string that is returned also must use this custom allocator,
and is incompatible with standard strings.  I guess that's not
surprising, however, now that I think about it...
