309	<	* Documentation?  You want DOCUMENTATION?
310	<	*
311	<	* Why all the potatoes below?
312	<	*
313	<	* To make a long story short, the original version of DumpWriter
314	<	* worked in the most inefficient way possible.  Node 0 would
315	<	* poke each of the node for an individual atom's formatted data
316	<	* as node 0 worked its way down the global index. This was particularly
317	<	* inefficient since the method blocked all processors at every atom
318	<	* (and did it twice!).
319	<	*
320	<	* An intermediate version of DumpWriter could be described from Node
321	<	* zero's perspective as follows:
322	<	*
323	<	*  1) Have 100 of your friends stand in a circle.
324	<	*  2) When you say go, have all of them start tossing potatoes at
325	<	*     you (one at a time).
326	<	*  3) Catch the potatoes.
327	<	*
328	<	* It was an improvement, but MPI has buffers and caches that could
329	<	* best be described in this analogy as "potato nets", so there's no
330	<	* need to block the processors atom-by-atom.
331	<	*
332	<	* This new and improved DumpWriter works in an even more efficient
333	<	* way:
334	<	*
335	<	*  1) Have 100 of your friend stand in a circle.
336	<	*  2) When you say go, have them start tossing 5-pound bags of
337	<	*     potatoes at you.
338	<	*  3) Once you've caught a friend's bag of potatoes,
339	<	*     toss them a spud to let them know they can toss another bag.
340	<	*
341	<	* How's THAT for documentation?
