Well, sending it to me will do you zero good, as my C skills are
awful.  Assuming it's a reasonable size, I think the list will take
it.

You can see things that happened in your own transaction, but nobody
else can.  If you're working READ COMMITTED, you can also see work
that other transactions commit while you were working.  Could any of
that be affecting you?  Unless your own function is doing something
with some cache, I am positive there's no cache issue here as you
describe it.
