If the file is too big to fit comfortably in memory, then both
of these will cause the same problem - lots of swapping, or an
"Out of memory" error.
Why do you think the simpler version might cause problems? In
both cases you're putting the entire file into memory.
Internally it's still being read one line at a time, too. In
practice, they both work fine.
