Comment:

 I have read this ticket twice now, and I fail to see the issue as being
 anything but a configuration error of some kind.

 If the objects are non-cacheable, the best thing to do would be to pass
 them in vcl_recv{} and be done with it.

 If you do not configure this, the normal waiting-list and "hit for pass"
 policies will kick in, and the problem you see is very likely the expected
 pile-up when the "hit for pass" object times out.

 Failing to spot anything that doesn't work as it should, I'm closing this
 ticket.
