The branch mostly survives. No crashes. However, two tests are failing. A test designed to stress rapid expiry and one that tests rapid ttl=0s - so in this case it's probably triggering the same bug.
The default VCL used (err, the fryer-default, not varnish-default) sets
beresp.do_stream = true, so unless a test explicitly disables it or
overrides the VCL, all the tests are run with that set.
I ran the rapid-expiry test with do_stream = false to check if that was
the issue. Disabling do_stream improved the result - the expected amount
of requests were received - but it still gave hitpass. When I
investigated the varnishlog with do_stream=true, it showed Stream
Error's. It also verified hitpass, though there was no reason that this
traffic should cause a hitpass.
As this is also a bit of a test on fryer (the below mail will be sent to
a public list of some sort soon-ish, instead of to myself) I will resist
explaining in detail what every test does - unless asked (do ask -
anyone!).
Grab a hold on me on IRC or mail if you want me to re-test or test with
some specific vcl or parameter, and I'll set it up.

PS: For the record: Master passes all of them, though the 4g-ones are
not properly measuring the traffic due to s_bodybytes issues.
