Retry whois request on "WHOIS LIMIT EXCEEDED"

I’ve seen:

  Scenario: whois(1) should work and go through Tor.                     # features/torified_misc.feature:29
    When I query the whois directory service for "torproject.org"        # features/step_definitions/torified_misc.rb:1
    Then the whois command is successful                                 # features/step_definitions/torified_misc.rb:17
    Then the whois standard output contains "The Tor Project"            # features/step_definitions/torified_misc.rb:27
      The whois standard output does not contain The Tor Project:
      WHOIS LIMIT EXCEEDED - SEE WWW.PIR.ORG/WHOIS FOR DETAILS

      .
      <nil> is not true. (Test::Unit::AssertionFailedError)
      ./features/step_definitions/torified_misc.rb:29:in `/^the (wget|whois) standard output contains "([^"]+)"$/'
      features/torified_misc.feature:32:in `Then the whois standard output contains "The Tor Project"'

I guess that this means that the exit node’s IP has made too many whois requests to that server => we should switch circuits and retry.
