... but I found a twelve-year-old paper about optimizing both
the exceptional and unexceptional execution paths ("A Study of
Exception Handling and Its Dynamic Optimization in Java," by
Ogasawara, Komatsu, and Nakatani).  It contains a table counting
how many exceptions are thrown by various programs.  Some excerpts:

     - Web browser opening one (2001-vintage) page: 2,892 exceptions
     - MP3 player starting and loading one file: 8,205 exceptions
     - Parse one XML file (size? complexity?): 17,640 exceptions
     - One program in SPECjvm98 (now obsolete): 242,318 exceptions

     Now: Speaking slowly, distinctly, and directly into the
carnation in my buttonhole, explain once again that you "dont
mind if there are a ton of emails."
