So this aroused my suspicions somewhat, since I was pretty sure I had
caused this somehow.  I am running the driver with the regex package by
Greg Lewis which patches the driver source to provide 3 new kfuns.  It was
written for 1.1 several years ago, but I was hoping it would work with
1.2.  (I originally found this from the DGD FAQ)

I hacked my lib to remove all references to the patched kfuns, and
restarted with clean driver source and re-ran my tests and all was well. 
It seems clear this package is doing something Bad[tm] to the driver.  I'm
not quite sure exactly what the interaction is, I can investigate deeper
if anyone needs me to ...

So now I will apologize for wasting peoples' time and bite the bullet and
implement this functionality as a driver extension using the supported
APIs provided by DGD.  The entire purpose is to expose the regular
expression functions the editor used internally by the driver as a set of
kfuns.

Thanks!
