Review request for mesos, Andrei Budnik, Jie Yu, Qian Zhang, and Vinod Kone.

Bugs: MESOS-6632

Repository: mesos


For the period between IOSB server is up and container process exec,
if the containerizer launch returns failure or discarded, the FD used
for signaling from the container process to the IOSB finish redirect
will be leaked, which would cause the IOSB stuck at io::redirect
forever. It would block the containerizer from cleaning up this
container at IOSB.

This issue could be exposed if there are frequent check containers
launch on an agent with heavy loads.
