    public List<TunnelInfo> listTunnels()

  Return a list of tunnels in the pool

  Returns:
    list of TunnelInfo objects

### needFallback

    public boolean needFallback()

  Do we really need more fallbacks? Used to prevent a zillion of them

### listPending

    public List listPending()

  list of tunnelInfo instances of tunnels currently being built

### getTunnelCount

    int getTunnelCount()

  duplicate of size(), let's pick one

### getSettings

    public TunnelPoolSettings getSettings()

### getSelector

    public TunnelPeerSelector getSelector()

### isAlive

    public boolean isAlive()

### size

    public int size()

  duplicate of getTunnelCount(), let's pick one

### addTunnel

    void addTunnel(TunnelInfo info)

  Add to the pool.

### removeTunnel

    void removeTunnel(TunnelInfo info)

  Remove from the pool.

### tunnelFailed

    public void tunnelFailed(PooledTunnelCreatorConfig cfg)

  This may be called multiple times from TestJob

### updateRate

    void updateRate()

### refreshLeaseSet

    void refreshLeaseSet()

  noop for outbound

### buildFallback

    boolean buildFallback()

  Returns:
    true if a fallback tunnel is built

### getLifetimeProcessed

    public long getLifetimeProcessed()

### countHowManyToBuild

    public int countHowManyToBuild()

  Gather the data to see how many tunnels to build, and then actually compute that value (delegated to the countHowManyToBuild function below)

### configureNewTunnel

    PooledTunnelCreatorConfig configureNewTunnel()

  Returns:
    null on failure

### buildComplete

    void buildComplete(PooledTunnelCreatorConfig cfg)

  Remove from the _inprogress list

### toString

    public String toString()

  Overrides:
