Ah ha... glad you knew!

*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 
if an xrefslave server were being fed a split stream (e.g. separate feeds 
for small and large articles) could do it, at least.  Most other scenarios 
I think the slave would be receivng articles in order.
