    unattached waiting for an appropriate circuit, before we fail it. (Default:

    2 minutes.)

**TokenBucketRefillInterval** __NUM__::

**TokenBucketRefillInterval** __NUM__ [**msec**|**second**]::

    Set the refill interval of Tor's token bucket to NUM milliseconds.

    NUM must be positive and either a divisor or a multiple of 1 second.

    Note that this option retains the configured bandwidth limits and refills

    token buckets only in ratio to the interval. This option will be ignored

    when Tor was built with Libevent's bufferevents enabled. (Default: 1 second)

    NUM must be between 1 and 1000, inclusive.  Note that the configured

    bandwidth limits are still expressed in bytes per second: this

    option only affects the frequency with which Tor checks to see whether

    previously exhausted connections  may read again. This option is

    if Tor was built with Libevent's bufferevents enabled. (Default: 10 msec.)

**TrackHostExits** __host__,__.domain__,__...__::

    For each value in the comma separated list, Tor will track recent
