This is nice while your configured internet connection works :)

At least under my scenario (behind a router), DNS setup to my ISP, If 
internet connection goes down, all programs that tries to resolve local 
hostname will "sleep" in connect(2) [called by getaddrinfo(3)], until 
reaches timeout.
I detected this while, while my internet conection fails, and I try to 
launch mc, it takes longer time, so adding back my hostname line to 
"hosts" workaround the issue.
