Just a side note: We can potentially "fix" this, but it doesn't mean this is a good practice. In fact, I think this is an anti-pattern to memcgs: resources should be preferably isolated between memcgs, or if a resource has to be shared between memcgs, it should be charged in a predetermined way, not randomly to one of the memcgs sharing it.
