Review request for mesos and Joris Van Remoortere.



Bugs: MESOS-5144

Repository: mesos


Without this change, `finalize()` terminates processes in the order
that they happen to be found when iterating over the `processes`
map. That means that if the GarbageCollector process is terminated
while any GC-managed processes are still running, those processes
will not be GC'd (i.e., they will be leaked).

Fix this by skipping the garbage collector process when iterating
over `processes` in `finalize()`, and then only terminating it after
all other processes have been terminated.
