 I switched to using the {{{restart}}} action in hopes of using multiple
 backends, but threads started dying with this message:
 {{{

 Here's my vcl:
 {{{
 backend s3 {
   .host = "207.171.183.117";
   .port = "80";
 }

 backend web1 {
   .host = "web1";
   .port = "80";
 }

 acl purge {
   "localhost";
   "127.0.0.1";
   "web1";
 }

 sub vcl_recv {
   set req.grace = 30s;
   if (req.request == "GET" && req.url ~ "\.(gif|jpg|swf|css|js)$") {
     if (req.restarts == 0) {
       set req.backend = web1;
     } else {
       set req.backend = s3;
     }
     lookup;
   }
   if (req.request == "PURGE") {
     if (!client.ip ~ purge) {
       error 405 "Not allowed.";
     }
     lookup;
   }
 }

 sub vcl_fetch {
   if (obj.status != 200) {
     restart;
   }

   set obj.grace = 30s;
   set obj.ttl = 1209600s;
   remove obj.http.Set-Cookie;
 }

 sub vcl_hit {
   if (req.request == "PURGE") {
     set obj.ttl = 0s;
     error 200 "Purged.";
   }
 }

 sub vcl_miss {
    if (req.request == "PURGE") {
      error 404 "Not in cache.";
    }

    if (req.http.user-agent ~ "spider") {
      error 503 "Not presently in cache";
    }
 }
 }}}

 And my start options:
 {{{
 $VARNISHD \
     -a 0.0.0.0:8000 \
     -T 127.0.0.1:8001 \
     -f $VARNISHCONF \
     -F \
     -h classic,150001 \
     -n $CACHEDIR \

     -s file,$CACHEDIR/cache,30GB \
     -p thread_pools=4 \
     -p lru_interval=3600 \
     -u $USER
 }}}

 I'm using {{{trunk at 2646}}}.
