A very small change to make eos somewhat work. no inner bins are checked.
Original commit message from CVS: A very small change to make eos somewhat work. no inner bins are checked. When an element fires EOS, the chain with that element is removed from the scheduler (marked inactive). If all chains are inactive, the bin fires EOS.
