[Haskell-cafe] Shootout favouring C

[Daniel Fischer]

First of all, we recently had a thread 'Shootout favouring imperative code', 
and I named this one after that. I certainly did not intend to insinuate 
(otherwise than mockingly) that the benchmarks were intentionally chosen so 
as to make one particular language look good/bad.
I apologize for all personal displeasure that followed.

Well, you asked for a _fictional_ motive, and jealousy is an excellent one. 
However as Brent already mentioned good old money...

Oh, sorry, but due to my slow and unstable connection to the net, 
I tend to look at fewer pages than I should (usually, after the third timed 
out request, I call it a day).

Hm, I might.
