I'd still like to see more discussion of how someone might actually use this feature. For
example, when you say "With these constraints operators can use a
global hard limit to contain resource limits set by users" -- how would the operator do this?
Presumably the operator cannot enforce global resource limits via a user-specified flag in
`ContainerInfo`.


docs/posix_rlimits.md (line 16)
<https://reviews.apache.org/r/53982/#comment227779>

    Is it actually possible to increase the soft limit above the hard limit? I don't believe
so.



docs/posix_rlimits.md (line 19)
<https://reviews.apache.org/r/53982/#comment227780>

    Using "contain" here is a bit confusing: I'd say "Operators can use a hard resource limit
to define the maximum amount of resources that can be consumed by a user; users can employ
soft resource limits to ensure that one of their tasks only consumes a limited amount of the
global hard resource limit."
