Should unsubscribe drain the channel?

From looking at the code, it looks as if the subscription readloop goroutine would block if the buffer fills up and then the client unsubscribes, leaving the channel and associated goroutine resources hanging around. Should unsubscribe drain sub.C?

@alaska Good question.This would be a good scenario to write a unit test for.
