 Replying to [comment:12 mikeperry]:
 > After writing a new interface to reliably get the top-level URL for an
 arbitrary third party nsIDocument, I discovered mozIThirdPartyUtil. It
 looks like it could be useful, but is still not exactly what we need here.
 Probably want to move my helper there, instead?
 I think so. I stumbled over it while adapting Dan Witte's cookie double-
 key patch to recent mozilla-central versions. And, yes, creating an own,
 central utility including helper methods to solve third-party questions
 for all parts of Gecko/Necko that need them seems quite reasonable to me.
