This isn't terribly unusual. According to http://en.wikipedia.org/wiki/ICFP_Programming_Contest it seems that C-family entries won in 1998, 2003, 2007, 2008, and now 2009.
It's really just about problem solving with programs and the winner gets the honour of their chosen programming language being declared the "programming language of choice for discriminating hackers".
I've had great fun attempting the problems in previous years and I'd encourage anyone who enjoys programming to have a go at it.
