When: *refresh_stale_hit and collapsed_forwarding are both active, and * the request contains a Cache-Control: no-cache directive, and * multiple requests arrive within the refresh_stale_hit window
the first request will go forward as expected, but subsequent requests get collapsed and effectively block, instead of being served from cache.
In other words, requests with CC: no-cache (or Pragma: nc, I'm guessing) effectively make *all* requests for the URI have a no-cache directive for the span of the refresh_stale_hit window, if collapsed_forwarding is on.
This isn't desirable, but it's not a huge deal; just thought I should mention it in case somebody got near this code again.
