There is no more SafeInterval, instead Intervals can be constructed with a RunQueue to use for expiring. PresentsDObjectMgr implements RunQueue. Client has a getRunQueue() method to get the client side RunQueue. git-svn-id: svn+ssh://src.earth.threerings.net/narya/trunk@3283 542714f4-19e9-0310-aa3c-eee0fc999fb1
