I've actually had this happen before, so unless it's changed in later patches, this remains true.
Every time the turn hits xxxx.0, the Value Improvement (VI) facilities take the resources remaining and increase them by the percentage. So if it's at 0kT, you are screwed. If it's at 100kT and you have a VI level 3, you get 103kT.
Thus, a "loophole" in a finite resource game is to balance your resource production facilities with VI facilities. Still gives the need for strategizing resource production more carefully, and you may have to move all resource production away from your homeworld(s) until you reach the level of VI mk1 in technology, or make use of somebody else's homeworld
--edit: Forgot, I'm fairly sure the max resources is somewhere between 3mT and 4mT.
