Modularize your functions and use a process unique (a|b) id; function_123 loaded at startup, function_124 loaded later, load the new module function_124, migrate data sets as needed, lock data sets, deregister function_X -> function_123, register function_X -> function_124, unlock data sets. If your code works properly, all you need is a function shell structure and you can continue this for a long time.

Hi Listmembers, Me and some friends have created a small irc network in which we are implementing ssl encryption between client and server. Our original ircd did not have this feature and now our new ircds do. The problem is in upgrading, the whole ircd must be killed and a new one started, which causes all clients to drop. My question is, is it possible to almost "hijack" a process, and switch the binary without losing the pid & tcp/ip connections? Is this a crazy and impossible idea, or has it been done? Any help would be appreciated!
