309 <     * Documentation?  You want DOCUMENTATION?
310 <     *
311 <     * Why all the potatoes below?  
312 <     *
313 <     * To make a long story short, the original version of DumpWriter
314 <     * worked in the most inefficient way possible.  Node 0 would
315 <     * poke each of the node for an individual atom's formatted data
316 <     * as node 0 worked its way down the global index. This was particularly
317 <     * inefficient since the method blocked all processors at every atom
318 <     * (and did it twice!).
319 <     *
320 <     * An intermediate version of DumpWriter could be described from Node
321 <     * zero's perspective as follows:
322 <     *
323 <     *  1) Have 100 of your friends stand in a circle.
324 <     *  2) When you say go, have all of them start tossing potatoes at
325 <     *     you (one at a time).
326 <     *  3) Catch the potatoes.
327 <     *
328 <     * It was an improvement, but MPI has buffers and caches that could
329 <     * best be described in this analogy as "potato nets", so there's no
330 <     * need to block the processors atom-by-atom.
331 <     *
332 <     * This new and improved DumpWriter works in an even more efficient
333 <     * way:
334 <     *
335 <     *  1) Have 100 of your friend stand in a circle.
336 <     *  2) When you say go, have them start tossing 5-pound bags of
337 <     *     potatoes at you.
338 <     *  3) Once you've caught a friend's bag of potatoes,
339 <     *     toss them a spud to let them know they can toss another bag.
340 <     *
341 <     * How's THAT for documentation?
