Best way to administer code updates to server daemon

[Daniel da Silva]

Hi,

I am writing a custom IRC server, and I was wondering would be the
best way to administer code updates to the daemon. Am I doomed to have
to restart the server every time I want to do an update (which would
disconnect all clients)? I don't mind doing something a little more
advanced if it means I can keep close to continuous uptime.

Thanks,
Daniel
