BTW, one of the way OpenVZ users determine how much memory they
need for containers is the following: they set the limits to
maximal values and then check the "maxheld" (i.e. the maximal level
of consumption over the time) value.
Currently, we don't have such in res_counters and I'm going to
implement this. Objections?
