Well, I blew my 1 day exploration into replacing with ptr_vector
without learning much except that we copy these SmartVector's around a
lot, including returning them from functions.  Unfortunately, we don't
do it very often in the unittests I was trying to do my timing with. 
Anyway, my explorations did tell me that I think replacing our
vector<shared_ptr> would probably work better as a shared_ptr<vector>.
 I'll look into it next time I have a day to blow.

Thanks anyway for a cool library.
