> Windows does not have the same notions of process hierarchies as Unix, and so killing
groups of processes requires us to make sure all processes are contained in a job object,
which acts something like a cgroup. This is particularly important when we decide to kill
a task, as there is no way to reliably do this unless all the processes you'd like to kill
are in the job object.
> This causes us a number of issues; it is a big reason we needed to fork the command executor,
and it is the reason tasks are currently unkillable in the default executor.
> As we clean this issue up, we need to think carefully about the process governance semantics
of Mesos, and how we can map them to a reliable, simple Windows implementation.
