Evaluating this still seems to be very slow.

Although with this particular exponent, no stack overflow occurs anymore, one can still crash axiom by choosing a higher exponent.

It seems that there are in fact two bugs: Axiom chooses the wrong signature (it should use integrate$RationalFunctionDefiniteIntegration?), and, as Waldek explained, axiom doesn't recognize integral powers as a regular functions. (#292)
