Review request for mesos, Alexander Rukletsov and Benjamin Mahler.


Bugs: MESOS-8970
    https://issues.apache.org/jira/browse/MESOS-8970


Repository: mesos


Description
-------

Up to C++17, the only ordering constraint on the evaluation of
expressions between synchronization points was that function
arguments shall be evaluated before calling a function.

This could lead to the situation where `std::move(futures)` could be
called before `await(futures.values())`, leading to a function call
on a moved-from object and thus undefined behaviour.
