Eric,

Is there a particular reason the above doesn't work?  I made an attempt 
to implement it a while back, but haven't convinced myself that signals 
and re-attaching a new struct pid to a running task is correct.

This should apply on top of Oren's ckpt v13 (based on 2.6.27-rc8). 
Consider this me floating the idea of adding support and I'll clean it 
up/rebase if you think it's useful.
