See these :
	This one is heavy-weight, whole process wrapping etc.
Also the implementation is on Linux.
Engineering fault-tolerant TCP/IP servers using FT-TCP.

This one is lightweight(in place logging),
works for TCP/IP and for pipes and the implementation is on
FreeBSD.
Service Continuations: An Operating System Mechanism for Dynamic
Migration of Internet Service Sessions.
