Running some more straces, I see that direct children of upstart (e.g.
pre-start scripts) cause delivery of SIGCHLD when dying, so the problem
looks like upstart not acting like the reaper for container processes.

Given that I have seen the call to vx_set_reaper and it looked fine, any
further things I can check before putting a printk everywhere I can?
