>>>I'm +1 for reference counting. It's going to be a little error prone 
initially (certainly much less error prone than the current system in 
the long run), but the pooling/arena idea is going to screw with all 
sorts of stuff within the AST and possibly in bits of Python/compile.c 
too. At least, all my attempts wound up looking that way :)
