I don't know what he expects, but I would do following:
1) split 10GB file into 4 chunks (read row by row until I fill about 2.5 Gb of memory)
2) sort each chunk in memory using quicksort (because it does not consume additional memory)
3) write every chunk back to the disk
4) using mergesort algorithm to merge data back to single sorted array reading from chunks by pieces and writting it simultaneously to the disk into the destination file.
