 Replying to [ticket:20212 gacar]:
 > Maybe Tor (or Tor Browser) could cap the number of new circuits opened
 within a time window. I can't think of a realistic use case for loading
 resources from tens of different hidden services.

 Here are two:
 * Checking the status of many hidden services
 * CDNs or other load-balancing techniques
