   // for object promotion. It counts only the bytes that the memory
   // allocator has not yet allocated from the OS and assigned to any space,
   // and does not count available bytes already in the old space or code
   // space.  Undercounting is safe---we may get an unrequested full GC when
   // a scavenge would have succeeded.
