Under the circumstance that there were constant and equal flow of incoming
reward tokens every block, this distribution mechanism would be equal to the
active distribution (distribute individually to all delegators each block).
However this is unrealistic so deviations from the active distribution will
occur based on fluctuations of incoming reward tokens as well as timing of
reward withdrawal by other delegators.
If you happen to know that incoming rewards are about significantly move up,
you are incentivized to not withdraw until after this event, increasing the
worth of your existing _accum_.
