=== Daemon ===

Tasks after restore should have lazy VMAs being backed by userfaultfd, the fd itself should be sent before resume to CRIU daemon and closed. This is that daemon who will monitor the UFFD events and repopulate the tasks address space. The daemon should be able to get pages from both -- remote and local images.
