Well based on this article the precise orbit of Halley cannot be predicted beyond a revolution and a half, therefore its future orbit cannot be predicted. The introduce a variable known as the Lyapunov exponent which sets a maximum limit on predictability.

Well, Halley isn't in a stable orbit, so... 

Some comets can go into orbital resonance. That's when things get bad, beause now you usually can't move them.
