For[i = 1.11111111111111111111, i > 0, Print[i = 2*i - i]]

This came to my attention (again), and I thought it might amuse
current readers of this newsgroup.

What looks like an infinite loop terminates with i==0 being true.  also 
i==2 is true.  (Tested in Mathematica 6.0; I don't have access to 7 yet.)
