-// This class should be used on a single thread, but it can be whichever thread
-// that you like.
-// Also, do not reuse the same instance. Once Start() is called, the instance
-// should not be reused.
-//
-// Usage:
-// * Create an instance with a consumer.
-// * Call Start()
-// * The consumer passed in the constructor will be called on the same
-//   thread Start was called with the results.
-//
-// This class can handle one request at a time. To parallelize requests,
-// create multiple instances.
