1. IMHO shared_ptr overhead is very much overrated. 
2. If you use it in a noncopyable fashion, then there is no run-time 
overhead. If you meant memory overhead, then I do not think it is 
something to worry about.
3. Untimately, you could try struct Foo : public 
pimpl<Foo>::value_semantics, boost::noncopyable.
