189	<	* Documentation?  You want DOCUMENTATION?
190	<	*
191	<	* Why all the potatoes below?
192	<	*
193	<	* To make a long story short, the original version of DumpWriter
194	<	* worked in the most inefficient way possible.  Node 0 would
195	<	* poke each of the node for an individual atom's formatted data
196	<	* as node 0 worked its way down the global index. This was particularly
197	<	* inefficient since the method blocked all processors at every atom
198	<	* (and did it twice!).
199	<	*
200	<	* An intermediate version of DumpWriter could be described from Node
201	<	* zero's perspective as follows:
202	<	*
203	<	*  1) Have 100 of your friends stand in a circle.
204	<	*  2) When you say go, have all of them start tossing potatoes at
205	<	*     you (one at a time).
206	<	*  3) Catch the potatoes.
207	<	*
208	<	* It was an improvement, but MPI has buffers and caches that could
209	<	* best be described in this analogy as "potato nets", so there's no
210	<	* need to block the processors atom-by-atom.
211	<	*
212	<	* This new and improved DumpWriter works in an even more efficient
213	<	* way:
214	<	*
215	<	*  1) Have 100 of your friend stand in a circle.
216	<	*  2) When you say go, have them start tossing 5-pound bags of
217	<	*     potatoes at you.
218	<	*  3) Once you've caught a friend's bag of potatoes,
219	<	*     toss them a spud to let them know they can toss another bag.
220	<	*
221	<	* How's THAT for documentation?
