Review request for mesos, Benjamin Mahler, Jie Yu, and Vinod Kone.


Bugs: MESOS-5944
    https://issues.apache.org/jira/browse/MESOS-5944


Repository: mesos


Description
-------

The StatusUpdateManager data is not recovered after reboot. This means
we can rely on flushes to the page cache to be sufficient for writing
status updates.


Diffs
-----

  src/slave/status_update_manager.cpp 9d16e0da92fdf2970ad3fd62036f6c5432eed774 

Diff: https://reviews.apache.org/r/50635/diff/


Testing
-------

Make check.
Started 500 tasks as quickly as possible on a single agent and verified the disk utilization
dropped significantly using `iostat`.


Thanks,

Joris Van Remoortere
