----------------------+-------------------
 I have seen an assert in current master (53e6f23)

 This happened once, I've not been able to reproduce it after ~6 subsequent
 runs.

 30 concurrent siege workers. (pulls ~170MB/s, 2x 1GE bonded)

 startup args:
 {{{
 /opt/varnish/sbin/varnishd -T localhost:6082 -a :6081
 -f /opt/varnish/etc/testsuite.vcl -smalloc,50M -p thread_pool_max=3000
 -p thread_pool_min=1000 -P /opt/varnish/var/varnishd.pid
 }}}


 vcl:
 {{{
 backend default {
         .host = "127.0.0.1";
         .port = "80";
 }
 sub vcl_backend_response { set beresp.do_stream = false; }## end
 }}}
