This one is easy to fix.  Simply have rnews do unbatching.  It won't be
very hard (I think, haven't really gotten into the code with this in mind
just yet) but it would save those thousands of execs (one for every article).
And since each exec has to spend a certain amount of time initializing itself
so it can properly insert the article, then there's an even greater savings.
