*nod* Incidentally, do you have any idea why I was the only one to notice
corrupt XOVER responses because of this? It seems like violating the
OVSTATICSEARCH contract would cause trouble more frequently.

I'm trying to imagine a scenario where this would be a problem...I suppose

for small and large articles) could do it, at least. Most other scenarios
I think the slave would be receivng articles in order.
