If same library uses c++ streams programer can choose between stream in
memory or for example temp-file. If you need to write lot of data to
stream may be it's better to have it on disk. Worst think is when you need
to pass stream (or file) to other non-c++-stream lib/process.

Btw, there can be also temp-directory (??).

I propose to create 2 (or more?) classes :
1. Class where file will be hidden, programer will use it by
        file-descriptor or any other handle.
        On Unix file would be removed after openning.
        On Win32 we can use tempfile's flag to CreateFile() - file will
        be also invisible ?.
        We don't need to care about removing file on destruction.

2. Class where we can extract file name and use it.
        File will be removed on destruction.
        We need to remember about file permissins etc.

3. Any idea ?
