 I can't find anything. Let's use common sense.

 Up/down scripts may be of several kinds, at least two:
 1. interface configuration tasks,
 2. some triggers for jobs.

 I belive that queue running has no relation to iface configuration
 and should be done in background. In some situations (as in my case),
 queue run may be meaningless if configuraion is not completed.

 Freezing may be caused by the DNS failure or some other result of
 network inaccessibility. It's good if such mail takes chance to be
 delivered, and IMHO there is no more trouble if some broken mail
 became frozen again.
