My final: < 27s, 7 lines, filesize average approaches 49_444_444

$ time ruby sample1 5_000_000 1_000_000_000 >t; wc -l sample1; wc -c t
elap 26.503 user 25.930 syst 0.542 CPU 99.88%
7 sample1
49444971 t

Or, chaining some operations: < 28s, 3 lines:

$ time ruby sample2 5_000_000 1_000_000_000 >t; wc -l sample2; wc -c t
elap 27.780 user 27.181 syst 0.592 CPU 99.97%
