* Application must initialize @c libcgroup using cgroup_init() before any
* other @c libcgroup function can be called. @c libcgroup caches information
* about mounted hierarchies (just what's mounted where, not the control groups
* themselves) at this time. There is currently no way to refresh this cache,
* i.e. all subsequent mounts/remounts/unmounts are not reflected in this cache
* and @c libcgroup may produce unexpected results.
*
* In addition, there is no way how to clean the cache on application exit.
*
* @todo this is very bad... There should be at least way how to refresh the
* cache and/or an option to refresh it automatically (does kernel provide
* any indication, when a filesystem is mounted/unmounted?). Dtto the cleanup
* on exit.
