246 <     * Documentation?  You want DOCUMENTATION?
247 <     *
248 <     * Why all the potatoes below?  
249 <     *
250 <     * To make a long story short, the original version of DumpWriter
251 <     * worked in the most inefficient way possible.  Node 0 would
252 <     * poke each of the node for an individual atom's formatted data
253 <     * as node 0 worked its way down the global index. This was particularly
254 <     * inefficient since the method blocked all processors at every atom
255 <     * (and did it twice!).
256 <     *
257 <     * An intermediate version of DumpWriter could be described from Node
258 <     * zero's perspective as follows:
259 <     *
260 <     *  1) Have 100 of your friends stand in a circle.
261 <     *  2) When you say go, have all of them start tossing potatoes at
262 <     *     you (one at a time).
263 <     *  3) Catch the potatoes.
264 <     *
265 <     * It was an improvement, but MPI has buffers and caches that could
266 <     * best be described in this analogy as "potato nets", so there's no
267 <     * need to block the processors atom-by-atom.
268 <     *
269 <     * This new and improved DumpWriter works in an even more efficient
270 <     * way:
271 <     *
272 <     *  1) Have 100 of your friend stand in a circle.
273 <     *  2) When you say go, have them start tossing 5-pound bags of
274 <     *     potatoes at you.
275 <     *  3) Once you've caught a friend's bag of potatoes,
276 <     *     toss them a spud to let them know they can toss another bag.
277 <     *
278 <     * How's THAT for documentation?
