[ Chris Townsend ]
* Change GetTasks to GetTasksRecursive so it searches all pids related
to a cgroup instead of just the first pid. (LP: #1386357)
[ Leo Arias ]
* On the cgroup manual test, make it clear that the command must be
run on the app.

Title:
Need to recursively search pids when detecting if pid is in a cgroup
Status in Ubuntu Application Launcher:
In Progress
Status in “ubuntu-app-launch” package in Ubuntu:
Fix Released
Bug description:
When searching through the list of pids to detect if they are in the
cgroup we care about, u-a-l currently only gets the top pid due to
calling GetTasks. Instead, we should call GetTasksRecursive to get
the whole list.
This is needed when trying to start up X applications inside a
container using XMir.
