433 <     * Documentation?  You want DOCUMENTATION?
434 <     *
435 <     * Why all the potatoes below?  
436 <     *
437 <     * To make a long story short, the original version of DumpWriter
438 <     * worked in the most inefficient way possible.  Node 0 would
439 <     * poke each of the node for an individual atom's formatted data
440 <     * as node 0 worked its way down the global index. This was particularly
441 <     * inefficient since the method blocked all processors at every atom
442 <     * (and did it twice!).
443 <     *
229 <     * An intermediate version of DumpWriter could be described from Node
230 <     * zero's perspective as follows:
231 <     *
232 <     *  1) Have 100 of your friends stand in a circle.
233 <     *  2) When you say go, have all of them start tossing potatoes at
234 <     *     you (one at a time).
235 <     *  3) Catch the potatoes.
236 <     *
237 <     * It was an improvement, but MPI has buffers and caches that could
238 <     * best be described in this analogy as "potato nets", so there's no
239 <     * need to block the processors atom-by-atom.
240 <     *
241 <     * This new and improved DumpWriter works in an even more efficient
242 <     * way:
243 <     *
244 <     *  1) Have 100 of your friend stand in a circle.
245 <     *  2) When you say go, have them start tossing 5-pound bags of
246 <     *     potatoes at you.
247 <     *  3) Once you've caught a friend's bag of potatoes,
248 <     *     toss them a spud to let them know they can toss another bag.
249 <     *
250 <     * How's THAT for documentation?
