It was **a ton** of work and discussions in public and among the maintainers,
in private. Anyway, if you have something which doesn't touch basic_streambuf,
keeps the get and put areas of basic_filebuf completely separate, with seeks
switching between reading and writing via state variables, then it's fine, in
principle.
