Heavy usage of net.Dial via net/http.Get gives errors stringifying as " Temporary
failure in name resolution" which corresponds to EAI_AGAIN returned from
getaddrinfo().
I expect net.Dial to retry on this error code.
I'm using 6g on Linux.
No effort is made to set the IsTimeout member of DNSError at the callsite
http://code.google.com/p/go/source/browse/src/pkg/net/cgo_unix.go#98, and an appropriate
IsTemporary variable is not available.
