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?
