> Given that multiple frameworks can be present on a machine at a time, and writing "node
drain" for each possible framework is an intractable task, it would nice if the slave-master
core had a means to tell frameworks that tasks were killed to drain a host.  Or possibly that
the slave was told to drain the host of all tasks (graceful shutdown, etc).

> This would make writing scripts for site-ops to do node maintenance much easier... :)
