Just now, some git server that is in the DNS rotation seems to have an 
issue,
$ telnet git.eu.kernel.org git
Trying 199.6.1.166...
Connected to git.eu.kernel.org.
Escape character is '^]'.
Connection closed by foreign host.

I thought it would be nice if git-fetch would retry the operation on 
the other DNS records that were returned if the connection breaks.

I think people who wrote git_tcp_connect_sock() in connect.c apparently
thought so, too.  It uses either gethostbyname() or getaddrinfo() and
iterate over the list of addresses returned from these functions.

Jan probably means trying next server even if Git protocol fails, not
just tcp connect.
