238 <   * Documentation?  You want DOCUMENTATION?
239 <   *
240 <   * Why all the potatoes below?  
241 <   *
242 <   * To make a long story short, the original version of DumpWriter
243 <   * worked in the most inefficient way possible.  Node 0 would
244 <   * poke each of the node for an individual atom's formatted data
245 <   * as node 0 worked its way down the global index. This was particularly
187 <   * inefficient since the method blocked all processors at every atom
188 <   * (and did it twice!).
189 <   *
190 <   * An intermediate version of DumpWriter could be described from Node
191 <   * zero's perspective as follows:
192 <   *
193 <   *  1) Have 100 of your friends stand in a circle.
194 <   *  2) When you say go, have all of them start tossing potatoes at
195 <   *     you (one at a time).
196 <   *  3) Catch the potatoes.
197 <   *
198 <   * It was an improvement, but MPI has buffers and caches that could
199 <   * best be described in this analogy as "potato nets", so there's no
200 <   * need to block the processors atom-by-atom.
201 <   *
202 <   * This new and improved DumpWriter works in an even more efficient
203 <   * way:
204 <   *
205 <   *  1) Have 100 of your friend stand in a circle.
206 <   *  2) When you say go, have them start tossing 5-pound bags of
207 <   *     potatoes at you.
208 <   *  3) Once you've caught a friend's bag of potatoes,
209 <   *     toss them a spud to let them know they can toss another bag.
210 <   *
211 <   * How's THAT for documentation?
