Maybe we need something with a mixture of features from scoped_ptr and 
shared_ptr.  scoped_ptr does everything that I need for a pimpl, except 
that it can't delete the incomplete implementation type.  shared_ptr 
can delete the incomplete implementation, but it has the unneeded 
overhead of reference counting and thread safety issues.  So, can the 
incomplete deletion feature of shared_ptr be extracted and added to 
scoped_ptr?  I have just had a quick look at the shared_ptr 
implementation to see how deletion works, but it's too clever for me to understand....
