Yeah, that's bad. We should probably be able to filter on the left side 
of the uid - like, only entries matching "foo:*" where "foo" is the 
user's share. Do we have that share information around somewhere when 
we make these calls or when we instantiate the history object?

Since this is essentially a bug in the history lib and not 
sync-specific, that'd be fine. Don't worry _too_ much about it, though.
