I don't know if it will do what you want since I think it was orphaned
a bit, but is in a working state, although a bit limited. Have a look at
http://cryopid.berlios.de/
It spawned out of an idea on software suspend development list. It will
suspend the whole process saving its state and will allow you to restart
it later.
IIRC it didn't get to the point of handling open file descriptors (and
thus sockets), and doesn't restore the process pid, but if your process
doesn't have open file descriptors and doesn't rely on its pid it may
work
