---------------------------------------
Some more notes on this from a related thread:
Task killing is not supported in the fine-grained mode on mesos because, in
that mode, we use Mesos's built in support for all of the control plane
messages relating to tasks. So we'll have to figure out how to support killing
tasks in that model. There are two questions, one is who actually sends the
"kill" message to the executor and the other is how we tell Mesos that the
cores are freed which were in use by the task. In the course of normal
operation that's handled by using the Mesos launchTask and sendStatusUpdate
interfaces.
