Hmm... EXECCOMM trouble...  Looking through the manual, it appears you
need to keep doing fetch next calls until SHVRET has SHVLVAR set--
It would appear EXECCOMM keeps it's pointer privately and it should be
exhausted before starting over.  I don't think a regular fetch call
will reset this pointer.  Try doing this and see if the problem goes
away.
