Because some LXC users run partially isolated containers (AKA.
application containers started with the lxc-execute command). Some of
the user code runs outside the container and some inside. Since
lxc-execute uses CLONE_NEWPID, it's difficult for the external code to
relate a pid generated inside the container with a task. There are
regular requests on lxc-users@ about this.
