Benjamin Bannier updated MESOS-8465:
------------------------------------
Description:
The implementation of {{DockerContainerizerProcess::usage}} checks on the
top-level whether the container is in {{DESTROYING}} state and returns a
failure in that case. It then possibly triggers compuation of the container
pid, and {{defers}} calculating the usage on that pid. The defered calculation
only makes sure that the container is not already destroyed.
If a user first requests the usage and then triggers container destruction,
{{usage}} could find the container not in {{DESTROYING}} state and would then
{{defer}} the usage computation. If the {{destroy}} is processed it would
trigger the actual killing of the container and mark the container as
{{DESTROYING}}. If the container is not fully destroyed the deferred usage
calculation could then pick up results not corresponding to the container
anymore.
