As I can see it even doesn't open the file, it just tries to get a 
current process file (/proc/curproc/file).

The traces for jailed and non-jailed calls are here (taken on two weeks 
old CURRENT, but 6.1 has the same problem):

If I do same think by hand I see the difference:

Inside jail:
$ ls -l /proc/curproc/file
lr--r--r--  1 user  users  0 Mar  3 21:26 /proc/curproc/file -> unknown

Outside jail:
$ ls -l /proc/curproc/file
lr--r--r--  1 user  users  0 Mar  3 21:27 /proc/curproc/file -> /bin/ls

Looks like kernel bug. Can somebody confirm the issue?
