I don't think we want to have a select loop separate from Nsock. It is
better to add domain socket support to Nsock for connect mode, and not
reimplement connect mode (along with everything else like delays and
telnet negotiation).

Unfortunately Nsock doesn't have listening support, or we would use it
for Ncat listen mode as well.
