We demonstrate that the classical helium atom exhibits algebraic decay of the survival probability in the autoionizing {\it eZe} configuration. Excitation towards asymptotic orbits of marginal stability is identified as the cause of the nonexponential decay. Since one electron travels along a bound Kepler trajectory of infinite excitation in these orbits, we argue that the classical decay ...
