218	–	* Documentation?  You want DOCUMENTATION?
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?
