I don't have a problem adding this kind of thing to the extension
filebufs. Either, both. Submit a patch, ChangeLog entry, the whole deal.

I do have a problem with adding fd/FILE accessors to std::basic_filebuf,
but this isn't what you are asking (at this point in the thread.)

I think you've already read the long, torrid history of why these were
removed from basic_filebuf. If not, I suggest you search this list in
google for these discussions, based on the creation date for
ext/stdio_filebuf. IMHO, until the standard C++ interface changes to add
these MF's, it's unlikely they'll show up in basic_filebuf again, no
matter how useful they are.
