----------------------+-------------------
 In an attempt at reproducing the VBO_waitlen() panic reported by "jw" on
 #varnish-hacking yesterday, fryer found another panic in master.

 gitref 645c1ca.

 vcl is default, only a backend definition.

 startup args:
 /opt/varnish/sbin/varnishd -T localhost:6082 -a :6081 -f
 /opt/varnish/etc/testsuite.vcl -smalloc,1M -p default_ttl=86400 -p
 thread_pool_min=100

 note the tiny malloc.
