Thanks Wez,

If all that happens is the query will fail, I can live with that. It's a
simple SELECT query called over and over again. If the integer wraps
around negative, I'm guessing that would probably have undesirable
effects. If not, then I can let it run forever. What I don't want is
something like a segfault. I'm considering making the application
restart itself periodically to clear out the cobwebs.
