I understand your concern. The main thing you should consider is that the space man does not see any time dilation in his local environment. Only external observers that are moving relative to him would determine that this is happening. And, as pointed out before, every one of them would come to a different answer depending upon their velocity relative to him. How would you determine which one has the right value?
Since the true value can not be determined, it is a measurement condition for the particular observer. It seems real to each one of these guys, but not overly important to the spaceman. He sees no time dilation within his ship.

This process could be continued indefinitely as long as the fuel lasts. I'm thinking here that "indefinitely" gets to be a very long time for the person in the spaceship; i.e., he never actually reaches the point that integrated acceleration will sum up to more than the speed of light, because time increasingly slows down for him until it effectively stops, and each new impulse takes longer and longer to complete.
