Really? I thought there are conservative GC's out there for C++ (and
even C, IIRC). It's not too much different from D's GC, actually. You
just override malloc/free in the library (or operator new and operator
delete, as the case may be), then have a GC thread scan the runtime
stack for roots.

Of course, only a conservative GC is possible, since you don't know
what's a real pointer and what's just an integer value that happens to
look like a pointer. But it's definitely possible.
