Cannot recover from `Connection refused` during connect/reconnect

[damienlevin]

Here is how it looks with actor logging turned on.
In this case I set the following rule :

sudo ipfw add 1 deny tcp from any to rds1.blabla.com 6379
and removed it latter on with
sudo ipfw del 1 deny tcp from any to rds1.blabla.com 6379

As you can see an Akka actor crashed and Brando don't get notified of it no Tcp.CommandFailed(_: Connect) sent.
