Thanks for your thoughtful comments Paolo.  Getting at least two  
brains (and hopefully a few more) thinking about these tradeoffs was  
exactly what I was hoping for.  I'm not sure what time frame is going  
to work for me to submit an alternative sso, but it is on my to-do  
list.  Perhaps with two alternative sso's that we can easily switch  
between, and/or tweak tuning parameters, we can get some of that real- 
world data you speak of.

Thanks for the swap tweak!  2x faster than a refcounted design on  
vector<string>::insert should give everyone a nice warm fuzzy! :-)   
After all, this really is one the places where a refcounted design  
was supposed to shine.  Nice job!
