using clone now .. still a problem, but I think this one should 
be easy to fix.

Wave objects can be very large, and there can be very many of 
them, so it is important to use extreme ways to eliminate 
duplication.

A complete set of outputs on a large circuit can easily be 
several gigabytes.

Many people, working only on small circuits, never see the 
problem.


Things like this usually take a few tries to get right.  Those 
"almost" tries are important steps on the way toward the one we 
want to keep, which is usually a lot simpler than most of the 
steps it took to get there.
