Comment (by lkarsten):

 I think this only applies to the socket-related operations?

 server.identity reads from heritage, and server.hostname is just
 a simple gethostname().

 Those two I believe should be safe to run in the background context.
 Have I forgot about something?

 I wonder if it could be confusing to use "server.hostname" in such a
 context, since that is in fact the fetching client's (varnish) hostname.
