Well, we could relax that restriction to allow RawMemoryAccess to
everything.

But I see your point.  I guess it doesn't.  But is that a bad thing?
If you want a garbage collector for gcj, why write it in Java?

It seems to me that Java doesn't have low-level memory access
features, by design.  C++ does, by design.  But you want to use Java
and not C++.  Like hammering a nail with pliers.
