Well, we are reusing the yum object, so that's probably why we're seeing this issue.  fwiw, I haven't been able to reproduce it yet.  As far as repo setup, we are doing:

            for repo in self.yumbase.repos.listEnabled():
                repo.metadata_expire = 60 * 60 * 1.5 # 1.5 hours, the default
                repo.mdpolicy = "group:primary"

(This is to set the cache back to a more aggressive level for actually doing an update - we're less aggressive for querying options for performance reasons)
