I had a similar thing happen to me once. (http://geekrant.wordpress.com/2007/11/29/holy-shmoly-ghc-does-some-magic-all... ) It bothered me at the time, but as Simon Marlow said in the comments:
I wouldn’t believe these figures too much. I couldn’t repeat the same effects here, but since this is such a tiny fragment of code, small effects are magnified, and differences can sometimes appear and disappear depending the day of the week.
