How to tarpit without loading conntrack modules?

(Please CC me as I'm not on the list)

Is it possible to use the TARPIT module without auto-loading conntrack 
modules and still leaving the machine able to make outbound connections? 
I tried the following and it didn't work. Using -m state --state 
ESTABLISHED loads the conntrack modules and therefore leaves the machine 
open to resource waste by connections that get tarpitted. Is there a 
solution? Or will I have to separate a machine for the purpose, and 
leave it unable to make outbound TCP connections?
