__getattr__ weirdness

[Greg Brunet]

In adding the ability to refer to field values using dbfFile.field
notation, I learned how to use __getattr__ and __setattr__ .  After some
trial and error, I got it working.  But as part of my trials, I added
some print statements to debug stuff.  The ones I added to __setattr__
work as expected, but the one in __getattr__ seems to get called just
under 1000 times for every __getattr__ call!

Something is obviously not right here - but I'm at a loss to understand
what's going on.  I've pared down my code to still show it happening &
included it below.  If you run this program & pipe the output to a file,
you'll get just under 14000 debug lines.  Any ideas?  Thanks!
