   OTP-8202  A new garbage collecting strategy for binaries which is more
	      aggressive than the previous implementation. Binaries now has
	      a virtual binary heap tied to each process. When binaries are
	      created or received to a process it will check if the heap
	      limit has been reached and if a reclaim should be done. This
	      imitates the behavior of ordinary Erlang terms. The virtual
	      heaps are grown and shrunk like ordinary heaps. This will
	      lessen the memory footprint of binaries in a system.
