-------------------------------------

Hi Steven, sorry just saw this isssue few minutes ago.
Not sure how this is related to executors, but looks like this is a generic slave problem where whenever we try to create a executor directory we always expect it to succeed.

> mesos-slave can encounter a variety of problems while attempting to launch a task.  If the task fails, that is unfortunate, but not the end of the world.  Other tasks should not be affected.
> However, if the task failure happens to trigger an assertion, the entire slave comes crashing down:
> F0501 19:10:46.095464  1705 paths.hpp:342] CHECK_SOME(mkdir): No space left on device Failed to create executor directory '/mnt/mesos/slaves/20150327-194449-419644938-5050-1649-S71/frameworks/Singularity/executors/pp-gc-eventlog-teamcity.2015.03.31T23.55.14-1430507446029-2-10.70.8.160-us_west_2b/runs/95a54aeb-322c-48e9-9f6f-5b359bccbc01'
> Immediately afterwards, all tasks on this slave were declared TASK_KILLED when mesos-slave restarted.
> Something as simple as a 'mkdir' failing is not worthy of an assertion failure.
