Uhhh... Cryopid was designed exactly for when you *don't* want to do that.

Software Suspend 2 is what you want to do something like that. Of course, your 
snapshot is only useful once, but this kind of low-level checkpointing (which 
is the same level as Cryopid) is always going to have that limitation.

Cryopid was what happened when I brought up per-application (eg, less than a 
full system) suspending on the SwSusp2 list some years ago. Pretty neat toy, 
but I don't think any real world use has come of it so far-- the main problem 
being that you lose any open I/O (other than stdio), which is generally the 
purpose of any application running.
