I ask the question because you're trying to break it up into an array
of lines -- which suggests that you're doing something with the data on
a line-by-line basis. If that's the case, why not read a single line,
do something with it, then read the next line? Then you don't need to
load the whole thing into memory first.
As I said before, though, it all depends on what you're trying to do.
