Ensure utilities with injectable target DispatchQueues deliver results serially #192

Right now, it would be possible to inject a concurrent DispatchQueue as the target queue, which would doubtless cause reliability issues. It's not a problem today, but we should probably make sure we guarantee serial behaviour by using DisaptchQueue.setTarget() on our own internal serial queue to guard against incorrect usage.
