i/o timeout

[whutlee]

Version = "0.1.2"
go version go1.7.4 windows/amd64
nameserver 114.114.114.114

when query some domain at same time “read udp i/o timeout” randomly occurred,
but use nslookup with host 114.114.114.114 can get the right result.

I think this problem most possibly be caused by the network lag that from your network to 114.114.114.114. You can try increment the timeout to mitigate the problem, https://github.com/kenshinx/godns/blob/master/etc/godns.conf#L19
