Addendum: if the number of samples is at least as great as the cache 
size, then it seems to work. I didn't actually write the density 
accumulator, so I'll need to check with the author to see if that's a 
precondition, or if there's some way we can return meaningful results 
with fewer samples. Matthias?

Still, a bug report would be good.
