188 <     * Documentation?  You want DOCUMENTATION?
189 <     *
190 <     * Why all the potatoes below?  
191 <     *
192 <     * To make a long story short, the original version of DumpWriter
193 <     * worked in the most inefficient way possible.  Node 0 would
194 <     * poke each of the node for an individual atom's formatted data
195 <     * as node 0 worked its way down the global index. This was particularly
196 <     * inefficient since the method blocked all processors at every atom
197 <     * (and did it twice!).
198 <     *
199 <     * An intermediate version of DumpWriter could be described from Node
200 <     * zero's perspective as follows:
201 <     *
202 <     *  1) Have 100 of your friends stand in a circle.
203 <     *  2) When you say go, have all of them start tossing potatoes at
204 <     *     you (one at a time).
205 <     *  3) Catch the potatoes.
206 <     *
207 <     * It was an improvement, but MPI has buffers and caches that could
208 <     * best be described in this analogy as "potato nets", so there's no
209 <     * need to block the processors atom-by-atom.
210 <     *
211 <     * This new and improved DumpWriter works in an even more efficient
212 <     * way:
213 <     *
214 <     *  1) Have 100 of your friend stand in a circle.
215 <     *  2) When you say go, have them start tossing 5-pound bags of
216 <     *     potatoes at you.
217 <     *  3) Once you've caught a friend's bag of potatoes,
218 <     *     toss them a spud to let them know they can toss another bag.
219 <     *
220 <     * How's THAT for documentation?
