219	<	*
220	<	* Why all the potatoes below?
221	<	*
222	<	* To make a long story short, the original version of DumpWriter
223	<	* worked in the most inefficient way possible.  Node 0 would
224	<	* poke each of the node for an individual atom's formatted data
225	<	* as node 0 worked its way down the global index. This was particularly
226	<	* inefficient since the method blocked all processors at every atom
227	<	* (and did it twice!).
228	<	*
229	<	* An intermediate version of DumpWriter could be described from Node
230	<	* zero's perspective as follows:
231	<	*
232	<	*  1) Have 100 of your friends stand in a circle.
233	<	*  2) When you say go, have all of them start tossing potatoes at
234	<	*     you (one at a time).
235	<	*  3) Catch the potatoes.
236	<	*
237	<	* It was an improvement, but MPI has buffers and caches that could
238	<	* best be described in this analogy as "potato nets", so there's no
239	<	* need to block the processors atom-by-atom.
240	<	*
241	<	* This new and improved DumpWriter works in an even more efficient
242	<	* way:
243	<	*
244	<	*  1) Have 100 of your friend stand in a circle.
245	<	*  2) When you say go, have them start tossing 5-pound bags of
246	<	*     potatoes at you.
247	<	*  3) Once you've caught a friend's bag of potatoes,
248	<	*     toss them a spud to let them know they can toss another bag.
249	<	*
250	<	* How's THAT for documentation?
