Memories of clearing mmdf channels...

(I was a CSNET techie from 1984-1988, which meant I was on-call about one
week in four -- during the various ARPANET congestion collapses this often
meant being paged and dialing into relay.cs.net to manually start clearing
mmdf queues -- usually around 2am -- and often because UUNET was overloaded
and the queue would back up to CSNET).

Fun memories...
