Certainly, numbers from actual benchmarks would be useful. In order to make these
comparisons easier, next weeks I will add to the v7-branch basic_string an
alternate base-class implementation which avoids reference-counting (+ simple
short-string optimization and needed changes to strings in exceptions classes).
Will be useful also to start evaluating various options for forms of simulated
move-semantics that should extend somewhat the range of application also to 
non-MT. All-in-all I would probably advice against the idea of opening a separate
PR - the performance issue is *well* known, in the abstract.
