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?
