    Referencing a single reject-all policy
    
    Oddly, the only exit policy I can find with greater than five occurances is the
    reject-all policy. Maybe a scripting bug. Reguardless, referencing a single
    reject-all instance saves us a little memory (1.3 MB with the present
    consensus, which is 1.6%).
