#880: Error when pushing 5G objects through Varnish
--------------------+-------------------------------------------------------
 Reporter:  perbu   |       Owner:       
     Type:  defect  |      Status:  new  
 Priority:  normal  |   Milestone:       
Component:  build   |     Version:  trunk
 Severity:  normal  |    Keywords:       
--------------------+-------------------------------------------------------
 Made a file with a huge (5G) hole in it. Nginx serves it, tried to get
 varnish to cache it. "curl -o /dev/null" as a client.

 Running trunk as of now:
 {{{
 ./varnishd -a 0.0.0.0:8080 -b localhost:80 -d -s malloc,7G -T
 localhost:2001
 }}}
 Crashes like this:
