Turns out that there was a link out there which had been broken for some time and last week, the cache-control was bumped down from 3 days to 5 minutes (wasn't supposed to be 3 days).  In either case, it was an rss feed that was timing out, I guess ... munin didn't show apache connections lingering, so I'm not sure why varnish was holding these references open.  Anyway, fixing a rewrite in apache solved the error, which in turn solved the problem in varnish ... false alarm.
