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 crtools about that.
* CR_STATE_RESTORE_SIGCHLD - Restore SIGCHLD handlers
* CR_STATE_COMPLETE - All handlers were restored, origin processes can be resumed.
* 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 crtools about that.
* CR_STATE_RESTORE_SIGCHLD - Restore SIGCHLD handlers
