That paper is from 1993. Hard to believe that it took such a long time to find a concrete pathology in a Newtonian system. Now the question is whether these blowups only occur on initial condition sets of zero measure.

John Baez also has a nice, accessible series of articles called "Stuggles with the Continuum" [0]. As a side product, it gives a nice perspective on the development of modern physics as a series of attempts to fix these infinities (only to create more subtle one).
