----------------------+-------------------
 Running trunk (as of aug 9, 2012) with the following settings:

 {{{
 $ varnishd -d -n /tmp/trunkTMP -a :8081 -b kly.no
 }}}

 I consistently get assert errors when I throw traffic at it. This only
 happens when I throw some moderate amount of requests over the same
 connection. The current example uses 502 GET requests and the assert is:
 {{{
