Description

The slave can optionally be put into its own cgroups for a list of subsystems, e.g., for monitoring of memory and cpu. See the slave flag: --slave_subsystems

It currently refuses to start if there are any processes in its cgroups - this could be another slave or some subprocess started by a previous slave - and only logs the pids of those processes.

Improve this to log details about the processes: suggest at least the process command, uid running it, and perhaps its start time.
