on dump and live with the fact that we're generating own events on restore.
== Chopping the knot ==
Here are possible ways to resolve the situation
* when dumping files gather fsnotify and ghost file descriptors into separate lists and dump them at the very late stage; then read out notify events from fsnotify descriptors
* when restoring files collect fsnotify descriptors into a root criu task deferring theis restore until all other files (from every child process) are restored; then restore notifies and read out all generated events
both ways require significant rework of CRIU design so for a while we simply print out a warning if fsnotify queue is not empty and continue processing.
