178 +   * Documentation?  You want DOCUMENTATION?
179 +   *
180 +   * Why all the potatoes below?  
181 +   *
182 +   * To make a long story short, the original version of DumpWriter
183 +   * worked in the most inefficient way possible.  Node 0 would
184 +   * poke each of the node for an individual atom's formatted data
185 +   * as node 0 worked its way down the global index. This was particularly
186 +   * inefficient since the method blocked all processors at every atom
187 +   * (and did it twice!).
188 +   *
189 +   * An intermediate version of DumpWriter could be described from Node
190 +   * zero's perspective as follows:
191 +   *
192 +   *  1) Have 100 of your friends stand in a circle.
193 +   *  2) When you say go, have all of them start tossing potatoes at
194 +   *     you (one at a time).
195 +   *  3) Catch the potatoes.
196 +   *
197 +   * It was an improvement, but MPI has buffers and caches that could
198 +   * best be described in this analogy as "potato nets", so there's no
199 +   * need to block the processors atom-by-atom.
200 +   *
201 +   * This new and improved DumpWriter works in an even more efficient
202 +   * way:
203 +   *
204 +   *  1) Have 100 of your friend stand in a circle.
205 +   *  2) When you say go, have them start tossing 5-pound bags of
206 +   *     potatoes at you.
207 +   *  3) Once you've caught a friend's bag of potatoes,
208 +   *     toss them a spud to let them know they can toss another bag.
209 +   *
210 +   * How's THAT for documentation?
