add ObClientTimeHeap. This is a max-heap of the clients based on their user times. this only includes the clients whose user time is not CurrentTime. the maximum from this heap replaces the client_last_user_time variable, so that you always have the latest time, not the last time that was changed.
hoefully it works, so far it seems to.
