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?
