rather than waiting and later unsharing.

This "makes the creation of a new cgroup early enough that the existing
cgroup mounts are visible.  Which means any fancy permission checks
I dream will work on a future version of liblxc."

This also includes what should be a tiny improvement regarding netns,
though it's conceivable it'll break something.  Remember that with new
kernels we need to unshare netns after we've become the root user in the
new userns, so that netns files are owned by that root.  But we were
passing the unfiltered handler->clone_flags to the original clone().
This just resulted in a temporary extra netns generation, but still
worked since our target netns, which we passed our devices into, was
created late enough.

The returned value from snprintf() should be checked carefully.

This bug can be leveraged to execute arbitrary code through carefully
constructing the payload, e.g,

lxc-freeze -n `python -c "print 'AAAAAAAA' + 'B'*959"` -P PADPAD -o /tmp/log

This command running on Ubuntu 14.04 (x86-64) can cause a segment fault.
