[ZODB-Dev] [BTrees] Inconsistent equality checks

[Dieter Maurer]

I learned yesterday that "BTrees" and friends ("Buckets", "Sets",
"TreeSets") do not define the standard equality check for
mappings/sets (but compare by identity).

Looking for an alternative, I met the following inconsitency:

	a= OOSet((1,2,3))
	b= OOSet((1,2,3))
	a.keys() == b.keys()
	--> 1

	a= OOTreeSet((1,2,3))
	b= OOTreeSet((1,2,3))
	a.keys() == b.keys()
	--> 0

We have the same inconsistency for "OOBucket", "OOBTree" and
"items".
