I was thinking about that one - it's not obvious to me from the code
how this "explicitly checking for dups" would be done or let's say how
rhashtable differentiates. But since it seems to work for Ben until
hitting a certain number of identical keys, surely that's just me not
understanding the code rather than anything else :)
