Re: Review Request: Added cgroups::hierarchies to list the currently active hierarchies and cgroups::internal::cloneCpusetValues in order to copy cpuset.cpus and cpuset.mems from a parent to a child cgroup. Also updated code to use path::join as appropriate.

    Any reason for the 'cgroups::' prefix on the read/writeControl calls here?

    1. The call to path::join("/", cgroup) is quite strange, it will 
essentially just prepend a "/" to the cgroup relative path, which seems wrong 
to me.
    
    2. Is it expected that there's always a parent in this call? Otherwise 
seems

    Thanks for this, I seem to recall making some clunky join calls that I 
should fix.
