Override Net::Server's HUP handling, just restart children. #20

Closed mpaperno closed 6 years ago

Yes, that looks good. Does the right thing on boot, and when manually sending SIGHUP.

You can see the PIDs change as the children are restarted, and the signal is logged.

Thanks. Yes, same results here with kill -HUP on Mint 18.3 and latest Net::Server (2.009).
