Would this option allow for me to checkpoint an IRC daemon when the clients connected to it aren't also being checkpointed? That was my interpretation of the description contained in the --help flag in the configure script. If that is incorrect, could you please give a proper explanation? If this isn't the correct method to handle network connections where both sides aren't checkpointed, is there a way to accomplish this?

The configure flag "--enable-external-socket-handling" pertains to an older piece of code. This option hasn't been exercised lately and is broken due to benign negligence. It has been on our todo list to replace this code with a newer design that uses DMTCP modules but has been low priority until now. If this flag is desired, then we will be happy to raise the priority and provide you with the solution over the next few days. Is this something you would want to have in DMTCP rather sooner than later? If so, please let us know and we will find a workaround.
