On the other hand, I do have other tables to worry about on my system...

I read up on -F during upgrade; that's why I decided to take it out;
default install from OpenBSD packages has this option included in suggested
startup script.

I was just confirming that this option accounted for all the time
difference in processing of my script.

I plan to investigate the impact of using transactions without -F in the
near future.

Thanks for the help guys. I've been unable to access email for a couple of
days. Sorry about delay in replying.
