Milestone:  Varnish 3.0 dev  |   Component:  varnishd

 For vcl_pass:

 According to documentation, vcl_pass does not cache the response nor
 should it remain in memory but passed, as in pipe, to the client.
 {{{
 Called upon entering pass mode. In this mode, the request is passed on to
 the backend, and the backend's response is passed on to the client, but is
 not entered into the cache.
 }}}

 However when running vcl_pass on a large file, it is still loaded into RAM
 - without even checking if it even fits into it and thus causing the
 kernel to OOM-kill random tasks.
