Review request for mesos, Benjamin Hindman, Ben Mahler, and Vinod Kone.


Bugs: MESOS-937
    https://issues.apache.org/jira/browse/MESOS-937


Repository: mesos-git


Description
-------

Description in JIRA: "Between the execution of 
ProcessWatcher::~ProcessWatcher() and its base class destructor 
Watcher::~Watcher(), the pure virtual method Watcher::process() can be invoked 
by WatcherProcess::event()."

By eliminating WatcherProcess this problem is resolved.
