261     * Documentation?  You want DOCUMENTATION?
262     *
263     * Why all the potatoes below?  
264     *
265     * To make a long story short, the original version of DumpWriter
266     * worked in the most inefficient way possible.  Node 0 would
267     * poke each of the node for an individual atom's formatted data
268     * as node 0 worked its way down the global index. This was particularly
269     * inefficient since the method blocked all processors at every atom
270     * (and did it twice!).
271     *
272     * An intermediate version of DumpWriter could be described from Node
273     * zero's perspective as follows:
274     *
275     *  1) Have 100 of your friends stand in a circle.
276     *  2) When you say go, have all of them start tossing potatoes at
277     *     you (one at a time).
278     *  3) Catch the potatoes.
279     *
280     * It was an improvement, but MPI has buffers and caches that could
281     * best be described in this analogy as "potato nets", so there's no
282     * need to block the processors atom-by-atom.
283     *
284     * This new and improved DumpWriter works in an even more efficient
285     * way:
286     *
287     *  1) Have 100 of your friend stand in a circle.
288     *  2) When you say go, have them start tossing 5-pound bags of
289     *     potatoes at you.
290     *  3) Once you've caught a friend's bag of potatoes,
291     *     toss them a spud to let them know they can toss another bag.
292     *
293     * How's THAT for documentation?
