Pat, John -- that was it. Thanks!

I'm still looking for the issue in the MoleculeSelection test. I found
one leak -- the pick command observer was not being removed, so a

  picker->RemoveObserver(com.GetPointer());

cleared up quite a few of the leaks, but many still remain (Believe it
or not, this list has been shortened!):

I'll keep digging ;-)
