Comment 9 for bug 699264

First, a few technical notes... If you want to change the FSF's address in the headers, please do so as a separate patch; such a change has nothing to do with this bug. Please don't include changelogs *inside* the sources, that's what commit logs are for. The sources say what *is*, not what *was*. Please put a space after #include.

As for the patch itself - you go through a *lot* of effort to re-implement <stdio.h> just to handle a case which should, ideally, never happen. We already do regular backups. I feel this change will make the code much harder to maintain, with little benefit to the end user. Is this change really justified?
