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.
If you have a case where leaking a few KB creates a serious problem, I'd 
like to learn about it.
