Loadmission()

Quick questin, when calling this function, is there any cleanup occuring? I'd doing an RPG, for quick load times i have stuff broken up into many small missions, example... going from a downstairs to an upstairs. The missions are very small and take no time to load by calling the loadmission from script. I do not want it to clear textures and other resources, I don't think so but does simply calling this function invoke the texture and resource flushes?
