well, in subst_uri() there is no need because the result->s chunk is 
transferred to msg->new_uri (and freed later from there); in 
subst_user(), the result->s chunk was copied by the SET_USER_T action, 
so we need to free it also.

this scheduling is done by kernel and there is no guarantee of a uniform 
distribution in case of low traffic.

you mean a process (there are no threads in openser). it might be a
