[ic] Interchange using lots of cpu...

In fact, when using [benchmark] on nearly every line, it seems that the
problem is not related to 'firing up perl'.  A single occurrence of
	[ARTICLE-param col10]
for example can take 0.07 seconds during initial loop iterations on 'large'
result sets.  A bit surprising.  If you want to dump out the content of 10
fields like that, voila, 0.7 seconds PER ROW, gradually speeding up as
results are emitted.  The last couple of hundred rows fly by, so unless
you process more than that you won't notice the problem.

As that seemed so fundamental I gave up on that approach and just dumped
the [query] results out in a single [perl] tag -- it now runs 100x faster
at least.

Now I've got to try and convince my colleagues that interchange is not
simply a toy.  If we end up doing everything in perl anyway, why use
interchange?
