  # I'm not sure if it's very useful to monitor the varnishd memory usage,
  # because it writes the pid of the varnishd parent process in it's pid file,
  # so I assume that's what god is monitoring, and the varnishd parent starts
  # a child process to do the real work.
  # Also, the child process allocates all cache storage with malloc, so the
  # VSS size can get very large and depends on the amount of storage 
  # configured. It relies on the OS to page unused portions to disk, but at
  # the moment we don't have much swap configured (just using the defaults
  # from Eric Hammond's base image).
