Forgive me if I am a bit dubious about these numbers.

I have added a sys.excepthook in the Lib/site.py file
on the PC where I do most of my work.  It logs uncaught
exceptions (except in interactive mode).  In a week or two,
I should have some real numbers to share.

Obviously this is a crude and subjective measurement,
but it's better than (ahem) nothing.
