 From the TODO file:
 {{{
   - Specify exit policy for machine conditions?
     - short_policy_t looks good, except for its flexible array member :/
       - Can we make our own struct with a small, fixed number of policy
         entries? Say 3-4? Or is that a bad idea to lose this flexibility?
     - Check conditions based on attached streams on the circuit
       - Accept should mean "only apply if matched"
       - Reject should mean "don't apply if matched"
       - If a policy is specified, Reject *:* is implicit default (so
 reject
         policies need an Accept entry).
       - With no policy, Accept *:* is implicit default.
 }}}
