  1. ct: execute CRIU restore with the --restore-detached option 

    In this case CRIU will exit after restoring processes. Here is
no reason to wait the init process.

  4. cr: use the RPC protocol for communication with criu 

    criu swrk is a special mode when we don't want to execute a service,
but want to use RPC.

Here is more details:
http://lists.openvz.org/pipermail/criu/2015-March/019400.html

Another good feature of this mode is that we don't need to create
action scripts and we will be able to remove the hack with saving StdFds.

criu swrk is supported starting with CRIU 1.5.1.
