Description:
 def check_cgroup_availability(wait=1):
 """ Basic utility to check the availability and permissions of cgroups. This will log some warnings for the user if necessary. On some systems, daemons such as cgrulesengd might interfere with the cgroups of a process soon after it was started. Thus this function starts a process, waits a configurable amount of time, and check whether the cgroups have been changed. @param wait: a non-negative int that is interpreted as seconds to wait during the check @raise SystemExit: if cgroups are not usable """
