Right next door (oops, city):

What is EPCKPT?
EPCKPT is a checkpoint/restart utility built into the Linux kernel.
Checkpointing is the ability to save an image of the state of a
process (or group of processes) at a certain point during its
lifetime. Checkpoints are important to a wide range of applications.
The most common uses for checkpointing are:
* Fault-tolerance
* Applications trace/Debugging
* Rollback/Animated playback
* Process migration
Our main interest right now is process migration. So, we optimized
EPCKPT to make process' image the smaller possible, so migration costs
would be low.
