Bug Description

== SRU ==
Rationale: LXC 1.1 and higher mangles the process env to be able to re-title itself, breaking the environment for sub-processes in the process
Test case: Spawn a container and check /proc/self/environ
Regression potential: Worst case scenario is we stamp on a different part of the process memory leading to similar but different breakage. It's been tested not to be the case though, change comes from upstream.

== Original bug report ==
I have a script using the Python3 LXC API that starts up a container. If I use an Upstart job to call the script, the $PATH env var is getting clobbered and the container fails to start.
