Looks like the entry _was_ cached. But at the time of possible re-use
was decided against due to the prior caching failing to set the expiry
to the receiving time + negative_ttl.
I think the (expires==0) in negativeCache() should be (expires<=0)
For my interest, What are the HTTP headers for that 404 message?
