Yes, I think this is better solution than my original suggestion
(which was identical to Microsoft's implementation of the new_handler)

Actually, my favorite variant is:

 typedef void*     (*new_recover)( size_t ) ;

"operator new" just returns whatever new_recover returns (supposing
new_recover returns).  With, of course, the qualification that
new_recover could call operator new (for example, if it had made more
memory available), and return the results of that call.
