  Levin (gr-qc/9910040) has shown that spinning compact binaries can be chaotic
at second post-Newtonian order. However, when higher order dissipational
effects are included, the dynamics will no longer be chaotic, though the
evolution may still be unpredictable in a practical sense. I discuss some of
the additional work that needs to be done to decide how this unpredictability
might affect gravitational wave detectors such as LIGO.
