Bibliographical note
Funding Information:While preparing this article, I was fomanate to receive comments and encouragement from a number of people, including G. Alexanderson, L. Arkeryd, P. Hilton, D. Huylebrouck, A. Marden, A. Odlyzko, M. Senechal, and R. Sharp. Warm words of thanks also go out to M. Pollicott (for his invitation to speak in Manchester), to the Isaac Newton Institute (for its financial support and hospitality), and to DeAnna Miller (whose serendipitous article sparked my interest in this matter).
