Yes, I'd like to know this as well. What would be an acceptable 
performance tradeoff?

And will this patch ever make a chance to be accepted into Ruby 1.8? g.c 
is very large, and it's generally hard to navigate in. I'd like to 
refactor a few things so that it's easier to navigate and to change, but 
this comes at the risk that my patch will conflict with future Ruby 1.8 
releases, or with other peoples' patches. If this gets merged into Ruby 
1.8 then that problem can be solved, so I'm really interested in the 
conditions for acceptance.
