I thought about making a qualification like this, but decided nobody would
feel the need to be such a smart-arse.

I'd say, "xreadlines will never hold more than a few KB of the file
in memory", but that's wrong if you have a file with a multi-megabyte line.

So, as you can see, I'm at a loss to describe just what xreadlines does,
but I'm sure it's a really wonderful thing.
