Subject: Re: Hash with two identical keys?

Looks to me that your keys are arrays.

My guess is that

p POOLS[self].keys[0].class

will return Array, instead of Symbol, which is what you're probably
expecting. So, the hash doesn't have identical keys.  It has two
different keys, each of which is a different array with identical
members.  Try

p POOLS[self].keys[0].object_id
p POOLS[self].keys[1].object_id

and you'll see the keys really are different.
