    Thanks for the bug report.

    Did you notice any leak in 'struct pids' also or just the pid_namespace ?
    If the pids are not leaking, this may be slightly different from the problem
    Catalin Marinas ran into:

    http://lkml.org/lkml/2009/7/29/406

    And the pid_namespace does not seem to reproduce for me, with out the
    'ls -al /proc/...' above, or with the simpler 'ns_exec' approach to
    creating pid namespace.

    I am going through the code for lxc-execute, but does it remount /proc
    in the container ?
