Can you really avoid having C++ objects that reference Emacs buffers
and strings?  Maybe you can, but not easily, I think, and not by
accident.

And on some platforms (although not on GNU/Linux, I think) malloc is
also replaced, so there's no "normal malloc space" per se.

In any case, I didn't pretend to have researched this issue and to
have firm conclusions.  I just said that it _should_be_ researched
thoroughly, before concluding that using C++, and in conjunction with
Qt on top of that, will not in itself get one in trouble that is
completely unrelated to experimenting with the display engine.
