: Taking a shapshot of a single process is not a very good idea since
: processes often depend on some other processes' data (not to mention the
: kernel). If you want to snapshot all info that is neccessary to restart
: a process, you have to snapshot all related processes and the state of
: the kernel. It's a much better idea to have general persistency and take
: periodic system-wide snapshots.
Yup. But throw a cluster into the mix and think about saving the state
of all those sockets. It's doable, just a pain in the butt.
