We need to be very careful to ensure that these error messages are processed, and I would argue this should be done asynchronously. So britney sends a request to the test runner workers via a queue. A worker picks this up and determines that neither it nor its peers on the same queue can handle it. It sends an error message to a separate queue that britney is reading from.
