  20 // BSProtocolThreadInvoker will forward all messages that are part of |protocol|
  21 // to its target |object| on the specified |thread| in the optional modes. This
  22 // allows a client to hold this as a delegate and write thread-safe code with
  23 // minimal work. The class also protects against the target |object| reentering
  24 // itself; if it or something it calls runs a nested run loop, the messages
  25 // will be queued until it would no longer reenter the object.
