> Right now, if a framework disappears then we just kill the executors, but they might have forked some processes, so at least with the process isolation module those forked processes will just keep running as normal, which is no good. Another problem with killing them is that they may want to clean up some resources. A solution needs two steps a) call shutdown() and wait a little for the executor to finish and b) check for any spawned processes and kill them (unless an isolation module that already does this is in use, e.g. LXC).
