[Interest] Strange undeletable QTemporaryFile. Is it a bug?

People can do many things wrong. This is no argument. If this function would have been private or protected, it would have been an alarm signal for me and I would have looked into the docs. For me was QTemporaryFile just a QFile with a little syntactic sugar for handling temporary files. It never occured to me that I had to read anything. Another very severe problem is that I wasn't even able to see my mistake under Linux. remove() apparently worked there. Of course, the file wasn't really removed there either, but there is no obvious way to see that.
