Hi,

dns2tcpd have a select within an infinite main loop that have a 500ms
timeout. This generates 6% of the wakeup events on my server which also
runs nginx, apache, nsd3 and dovecot among others. But when idling,
dns2tcp should do nothing.
The provided patch removes the timeout. It may not be the better fix,
but for my small use, it is perfect.
