I just compiled a 2.6.37 and tested with a simple 'sleep' inside a 
container and then stopped but the hang did not occur.
I also tried with an ubuntu container and busybox without problem.

I tried on kvm x86_64

At the first glance, I think it is not necessary. The lxc code does not 
rely on kernel code, so there is no dependency except the one provided 
by the linux header installed on the system. In any case, userspace code 
should not hang a system.
