241	<	* Documentation?  You want DOCUMENTATION?
242	<	*
243	<	* Why all the potatoes below?
244	<	*
245	<	* To make a long story short, the original version of DumpWriter
246	<	* worked in the most inefficient way possible.  Node 0 would
247	<	* poke each of the node for an individual atom's formatted data
248	<	* as node 0 worked its way down the global index. This was particularly
249	<	* inefficient since the method blocked all processors at every atom
250	<	* (and did it twice!).
251	<	*
252	<	* An intermediate version of DumpWriter could be described from Node
253	<	* zero's perspective as follows:
254	<	*
255	<	*  1) Have 100 of your friends stand in a circle.
256	<	*  2) When you say go, have all of them start tossing potatoes at
257	<	*     you (one at a time).
258	<	*  3) Catch the potatoes.
259	<	*
260	<	* It was an improvement, but MPI has buffers and caches that could
261	<	* best be described in this analogy as "potato nets", so there's no
262	<	* need to block the processors atom-by-atom.
263	<	*
264	<	* This new and improved DumpWriter works in an even more efficient
265	<	* way:
266	<	*
267	<	*  1) Have 100 of your friend stand in a circle.
268	<	*  2) When you say go, have them start tossing 5-pound bags of
269	<	*     potatoes at you.
270	<	*  3) Once you've caught a friend's bag of potatoes,
271	<	*     toss them a spud to let them know they can toss another bag.
272	<	*
273	<	* How's THAT for documentation?
