179	<	* Documentation?  You want DOCUMENTATION?
180	<	*
181	<	* Why all the potatoes below?
182	<	*
183	<	* To make a long story short, the original version of DumpWriter
184	<	* worked in the most inefficient way possible.  Node 0 would
185	<	* poke each of the node for an individual atom's formatted data
186	<	* as node 0 worked its way down the global index. This was particularly
187	<	* inefficient since the method blocked all processors at every atom
188	<	* (and did it twice!).
189	<	*
190	<	* An intermediate version of DumpWriter could be described from Node
191	<	* zero's perspective as follows:
192	<	*
193	<	*  1) Have 100 of your friends stand in a circle.
194	<	*  2) When you say go, have all of them start tossing potatoes at
195	<	*     you (one at a time).
196	<	*  3) Catch the potatoes.
197	<	*
198	<	* It was an improvement, but MPI has buffers and caches that could
199	<	* best be described in this analogy as "potato nets", so there's no
200	<	* need to block the processors atom-by-atom.
201	<	*
202	<	* This new and improved DumpWriter works in an even more efficient
203	<	* way:
204	<	*
205	<	*  1) Have 100 of your friend stand in a circle.
206	<	*  2) When you say go, have them start tossing 5-pound bags of
207	<	*     potatoes at you.
208	<	*  3) Once you've caught a friend's bag of potatoes,
209	<	*     toss them a spud to let them know they can toss another bag.
210	<	*
211	<	* How's THAT for documentation?
