Generic code uses raw syscall numbers for: - syscall_seized, to execute through parasite control needed syscall; - parasite_stop_on_syscall, to trap couple of tasks on needed syscall. As syscall numbers may differ (and differ for x86) between native and compatible mode, we need proper syscall wrapper here.

CRIU (Checkpoint and Restore in Userspace)
An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.
The project home is at http://criu.org.
Pages worth starting with are:
- Kernel configuration, compilation, etc
- A simple example of usage
- More sophisticated example with graphical app
