Yes you can do this, but it's not thread safe (unlike stateful 
sessions). The stateless session could be propagating data mid change 
and thus leaving the network invalid. So if you do this, which is not 
recommended practice, do make sure that you know that there are 
currently no valid executing sessions for that RuleBase.
