The garbage collector's (Boehm-Demers-Weiser?) mark algorithm
must know about MrEd's C++ objects.  How?  Does it start with
the BSS space and just follow every four byte boundary as if it
were a pointer?  Or does MrEd somehow inform the GC about its
global objects and the mark algorithm follows pointers or anything
that might be a pointer from there?

Can I do something in my C++ code to inform the GC about my objects,
so that they aren't collected?

Thanks,
