    engine: throttle outbound queries only when busy · 0b02bf5f

    resolver will always attempt to contact upstreams
    known to be bad if it's not busy.
    this fixes a problem on low-volume resolvers
    where a short connection outage could make
    resolvers deny resolving queries even after the
    connection is restored
