Guido will give up reference counting and the consequent immediate gc 
when but only when *someone* presents an implementation that does and 
and that runs faster.  Given the current ferment in dynamic language 
implementation, he just today wrote on pydev list "CPython's 
implementation strategy *will* evolve".  Whether that means R.C. goes 
away or not remains to be seen.
