Aaron Lehmann	6fb5c112d5	Make the broadcaster write messages to the observers in the same units they were written to the broadcaster ...

Aaron Lehmann	b8c40573a4	Clean up ProgressStatus ... - Rename to Broadcaster - Document exported types - Change Wait function to just wait. Writing a message to the writer and adding the writer to the observers list are now handled by separate function calls. - Avoid importing logrus (the condition where it was used should never happen, anyway). - Make writes non-blocking Signed-off-by: Aaron Lehmann <aaron.lehmann@docker.com>	2015-08-27 13:22:08 -07:00
