This sounds like a bug to me.  five:localsite should react like
five:traverseable, that is it shouldn't have any discriminator and if
you try running it more than once on the same class, the additional
calls should simply have no effect.

Of course with Zope 2.10 I believe we won't have this problem since all
ObjectManager's are IPossibleSite's to begin with.
