the argument can be any, e.g. a subselect. The subselect

they want to store some value in local variable, pass return value and
etc... So their life time should be longer than one instruction.
Probably we can call destructors for most of them then we are leaving
routine. But this won't help much as they are allocated in main query
MEM_ROOT anyway. So they all go to global thd->free_list.
May be we can use some other MEM_ROOT for this purprose ???
What else should we do for cleanup ?
cleanup_items() is called in sp_head::execute()
