"probably" is the word.  That's what I mean -- in C++, you can't even
tell which language constructs might be implemented with code which
under-the-hood is going to be doing dynamic memory allocation or other
async-cancel-unsafe operations.  "#include <iostream.h>"?
Constructors for static objects?  dynamic_cast?  const_cast??
