A process of restoring has a few global synchronization points:

`CR_STATE_FORKING`	Create tasks and restore group leaders
`CR_STATE_RESTORE_PGID`	Restore group IDs. Group leaders should exist in this moment and all helpers should be alive
`CR_STATE_RESTORE`	Wait helpers and restore a most part of resources. If anyone segfauls, its parent gets SIGCHLD and notify criu about that
`CR_STATE_RESTORE_SIGCHLD`	Restore `SIGCHLD` handlers
`CR_STATE_COMPLETE`	All handlers were restored, origin processes can be resumed.
