A bit off-topic, but let me remind about another problem before I forgot...

	# unshare -m
	# perl -e 'sleep'

Now "criu dump -t `pidof perl`" fails with

	Error (files-reg.c:821): Unable to look up the 22 mount
	Error (cr-dump.c:1580): Dump files (pid: 10822) failed with -1

So there are 2 problems:

	1. The error message is confusing and doesn't help to understand
	   whats going on.

	   "Fixed" by this patch.

	2. Well, it would be nice to handle this case too.

	   Left as an exercise for criu developers.
