Yes. Ordinarily, lines in text files aren't longer than a few hundred characters, leaking those, who cares? I got several space leaks of this kind in the past. They are very annoying. They are especially annoying if input comes from the outside world, where people can attack them to crash your program because of memory exhaustion.
That would likely be the case of long lines, wouldn't it? I have trouble imagining a scenario where `lines' holding on to a few hundred characters which could already be released causes a noticeable space leak, let alone memory exhaustion.
I talked about an _attack_! I provide a program that processes external data (say a webserver, for instance one for an ICFP contest) and someone feeds it intentionally with megabytes of text without any line ending.
